  1. Obviously Tomlin is a great coach and the other 48 are knowledgeable professionals. I'm not saying that I know the game more or could outcoach them. I'm saying apply science and math. There is something simple everyone is overlooking. Well Game Theory explained the Cold War and I saw an example where a goalie uses it to block left instead of right. But even though this is also strategy, Game Theory still applies. If Game Theory couldn't help make sense of complex decisions it wouldn't be useful. I have many other ideas to measure but I do not have access to game footage. So if anyone has access to any such game footage
  2. Thanks for the input, but I'm not far in left field here. But you are right I have to put it into something calculable. How bout this. I just heard you have to put pressure on Brady (the Patriot's quarterback), but he releases the ball too fast. So the game theory "decision" is to determine when Brady is throwing fast and when he needs more time for his receivers to get down field. The decision to make is stopping the small gains. The Steelers usually take away the deep allowing the short, but this doesn't work. The Pats march up the field with short passes. But the only way to stop such an offense is to solve when the Pats are short or long plays. My solution (recommendation (not mathematically proven)) is to make the receivers go deep. I say this because Brady is relying on his receivers to get open. The receiver goes short when the defender goes deep and will go deep if the defender tries to stop the short pass. So rush Brady if receivers go deep and don't rush Brady when you give up the short. This strategy correlates with Brady decision and time to release, and how he is allowing his receivers to dictate the march down the field. I know this sounds simplistic but I think we could test it scientifically. From my understanding game theory is simply decision making. I know not all football is logic, but the strategy is game theory even if it is too complex for math. But you guys insisted on a concrete example. Let me know if this is a more fundamental approach. I chose this example for a clear choice of when to rush Brady. Obviously the offense has the advantage. A few recivers going different routes and going deep or should would complicate the math. But I include this example if the Pats go undefeated this season this forum may be interested in how they are doing it once again.
  3. Yes the science of game theory. And how to design a football game scheme that will stop the Patriots offense. About 15 years ago there was an online Star Wars game. The Imperial forces strength far outweighed the Rebels. One Rebel-based player planned an attack the devestated the Imperial forces. It ruined the game but it should what an underdog can do. There is a branch of science called network science where the general public has access to the data. I'm saying if several thousand people were analyzing the game tape they would discover why the Pats always have better play calling. I know they have won the Super Bowl 6 of 8 times, but they have done it with different teams, often not the more talented teams. So I am asking is there a way to use science to insure the integrity of the game? Something that can be measured by the fans? Probality is out. I have read about people using computer football simulators. I don't know what they use. I have a $20 game I bought off Steam. But I end with this, with drafts and salary caps how is it possible for one team to dominate the game 20 years?
  4. Ok to show I don't just waste my time looking for patterns in factoring. I have also studied game theory. Not so much the rigorous math, but the protocols. With a little knowledge and possible outcomes you can make some good predictions. I don't know if my reference will be lost on those who don't follow American football but here it is. I predicted on January 10th 2019 that Antonio Brown would become a New England Patriot. I have proof in the YouTube video link following. But my simple approach to game theory does not end there. Simply put the Patriots are ruining football. What if we the fans could devise a game plan that would defeat the Patriots. We could use game theory and math. It would be a great challenge. youtu.be/SX1QAXp53f4 http://youtu.be/SX1QAXp53f4
  5. I've been told Linux is secure because the code is public. You se what is put on the system. In cryptography an open cipher is more secure than hidden. But is this true? The fact is we don't know what is going on when the computer is processing thousands or computarions. I warned a friend about software piracy. They just don't give software away it is loaded with viruses. I told him the movie files could hide viruses in the file. He says he knows it is virus free because he is extracting a pure movie file. I disagree because movie files are packaged with instructions for the codec. The question to ask is "is our Linux more secure?"
  6. What is the "logic" deleting the code. That is bad "syntax". Isn't the code the discussion? The reason to post code alone is to have the code be read entirely. But the code itself should not have been deleted. It erases the record of the post. I was going to reply to this post but didn't because I figured I'd kill it because of my previous thread where I claim I can factor semi Primes. I wanted to see what other more experienced coders thought.
  7. Thanks Sensei. This program is heading for a crash with large numbers. I believe float could handle large numbers but the Cmath library is limited in operation. Are there any math libraries on the net with easy implementation? I was thinking of programming it in Mathematica, but before it can be useful I have to compute the error.
  8. This is a program I wrote. It isn't very useful yet because I need a software library that handles large numbers. But if you read it you will see what I have been saying all along. Of course I could be wrong, but that goes without saying. I need some computer scientist to explain how I can run a program similar to this one with large numbers. /* This program utilizes factor patterns to estimate the value p in the N=p*q keys in RSA and other cryptography ciphers that use the product of semi-prime numbers. Note it is complex to program math into a programming language. Large values could easily crash this program. As an example I recommend testing 85 for N and 5 for x. Also note that finding the error between PNP and pnp_check is crucial to solving this problem. For this demenstration estimate is set to 7. Abviously to make this program usefull estimate must be determined exactly. For now this stands as a demonstration of the equation. */ #include "stdafx.h" #include <math.h> #include <iostream> using namespace std; int main() { bool testvalue = false; int PNP; double root, estimate = 7; float x, pnp_check; cout << "Input N the know product of 2 Prime numbers" << endl; cin >> PNP; do { cout << "Enter the small Prime factor of N as test value+." << endl; cin >> x; /* PNPcheck = sqrt[(((((x ^ 2) * (PNP ^ 4) + 2 * PNP ^ 2 * (x ^ 5)) + x ^ 8) / PNP ^ 4) * (((PNP ^ 2) / x ^ 2)))]; estimate = (2 * x ^ 5 / PNP ^ 2 + x ^ 8 / PNP ^ 4); */ pnp_check = (((( (x*x) * (PNP*PNP*PNP*PNP) + 2 * (PNP * PNP) * (x*x*x*x*x)) + (x*x*x*x*x*x*x*x)) / (PNP*PNP*PNP*PNP)) * ( ( (PNP*PNP) / (x*x) ))); root = sqrt(double(pnp_check)); if ((abs(root - double(PNP))) < ((estimate))) { testvalue = true; }; cout << "The root that compares to N is " << root << endl; if (root > PNP) { cout << "Chose lower x if program does not end." << endl; }; cout << pnp_check << endl; if (root < PNP) { cout << "Chose higher x if program does not end." << endl; }; } while (testvalue != true); cout << endl << endl << endl; cout << "The smaller Prime Factor is around " << x << endl; system("pause"); return 0; }
  9. Well there is some learning and fundamentals to the question. I wish I could locate the question and the specifications. But it is the usage of this programming exercise I don't like. Say there is a C++ you have this exercise, then you take Java you see this problem again. If I can find the exact problem, you might recognize it. I'm just trying to demonstrate that actual programming differs from the bank problem. One its first use it probably demonstrated arrays and memory, loops and program structure. You make a good argument, but trust me if you would have come across this as a final project you would agree that the curriculum needs updated. I've been researching and studying trying to improve my programming skills. But elementary and high schools have upgraded there STEM programs. I know some programming experience is better than no programming experience. However, the quality of a lot of colleges is too dumbed down. It does take some know how to organize the bank problem, but a high school student is spending hours to program a robot. (Yes I know adult students are pressed for time, but why isn't the curriculum similar to the high school's?) I have some learning in adult education. I know that curriculum design is serious stuff. I think that is the problem here. The instructor may well be an awesome programmer but he must evaluate us based on an established curriculum. The instructor must teach the curriculum good or bad. But I don't know how you would improve the class without better curriculum design and the ability of the instructor to modify curriculum. The better curriculum is possible. It is the leeway of the instructor to improve it. For example, a math class could have a recitation where students ask questions and bring up questions that both relate and explore the material. Then a lab where questions such as the bank problem are ask. The bank problem was actually designed well the first time it was ask. But if you search online classes you will see many students complain about it. Why this problem again? My code is supposed to do something cool.
  10. I was just wondering if anyone has come across this computer programming exercise. You are a programmer hired by a bank to manage several bank accounts. That isn’t always the exact description, but this question is standard for online courses. And from people I talk to they had the same question at traditional colleges. This is bad for uncountable reasons. This question even goes across different languages, such as C++ and when you learn Java it is the same question with different syntax. Not to mention a quick web search will answer the question. You are supposed to be a computer scientist and they give you a bank question. My complaint is that no one is writing proper computer science curriculum. I have taken classes how to teach adults and with my limited experience this question is an insult to the student. The thing is these programming classes aren’t teaching you to problem solve and program real solutions. Yes, I know there are better classes that a fifth grader is programming a robot and now has better programming skills than me. I know there are better questions that you can ask an adult programming student. I put this in the computer science, but this is also an education question. I get they want to demonstrate arrays and memory storage, but the truth is this is a disservice to the students. So, you pay to go to school and they teach you programming exercises that don’t go together. Then you graduate and you have to teach yourself how to actually program. Basically, what I’m saying is that a YouTube video or a Learn C++ book in 24 hours is more cost effective. How broad is this bank computer program? Has anyone here encountered it? BTW this bank exercises is usually a major project of the programming courses. Obviously I don't mean that it is just a simple exercise. This is a final project.

    Questions to Ask

    Well these are not directly Christian questions. They are (or were) what I question about life. You are right about the meaning of life opening a can of worms. My beliefs now is that the meaning of life is as debatable as proving a creator exists. I believe we make our own meaning. My goal was to share some questions. The intent was to see what others questioned. It can be religious or scientific. I know many questions have been ask since the beginning of humanity. However, I don't know with conflicting personal views if we are asking the same questions or just a result of life experiences. Many religions tell to share the faith. But we know arguing if God exists is exhausting and usually pointless. You have to respect people have their own beliefs. But are the asking the same questions? What do they value? Arguing seldom helps. On this forum the goal is debate so we can discuss the arguments. But it is the questions we ask or don't ask are the foundation of all our beliefs.

    Questions to Ask

    Think for a minute. Don’t think religion or science. Think belief. There is a difference between belief and religion. Do you believe there are other worlds? Not just in space planets but other dimensions such as string theory. Now you must decide if these worlds automatically exist or they were created. If the worlds were created, you must decide if the creator actually cares about the human race. If you do believe in a God that cares, you must decide if those teaching about him actually represent him. If you believe God doesn’t exist, you must question the meaning of life. I tried to remain unbiased here. But to me these are the questions I ask. Michio Kaku is correct in saying we can’t prove or disprove God. They only reason to argue is to try to influence someone’s beliefs. The arguing isn’t fighting. Debates can be fun. These questions are personal, and I don’t try and force my answers on you. The entire idea behind a religion is to believe in those answers that make sense to a person’s own experiences. I will say this. We don’t know of things we don’t know. I mean in science we find something new and don’t know much about it. It makes you question if it were there the whole time and how we could have not known about it before. Simply put, just because we haven’t experienced something, does not mean that a whole new world does not exist. Keep this in mind when you answer these questions. BTW, I do not claim these questions are original. I have studied many sources. I think Michio Kaku explained the question of who is right best when he was ask about religion. He has several Youtube videos. These are just the questions I feel I have been asking myself. It adds fun to the debate, instead of simply yelling because you agree or disagree. As far as I know no one has asked these questions on SFN before. That is, at least without open-ended questions. I'm sure we have all ask some of these questions before.
  13. [ x^4 + (2*x)/N^2 + x^10/N^4 ] ^(1/4) = x The brackets are the 4th root of N = x * y , the product of 2 Prime numbers x is the smaller Prime factor Example N = 85, x = 5, and y = 17 I apologize for the blunder above. But you need to understand I literally tried thousands of equations. So far this is my best. Check it for errors. Is anyone having any luck with other combinations? x^3 + 2*x^4/N^2 + x^6/N^4 = x^2
  14. I hope someone responds. I am serious. And to show that I am serious I offer the equation as far as I can simplify. [ x^4 + (2*x)/N^2 + x^10/N^4 ] ^(1/4) = x The brackets are the 4th root of We know N = 85, so solving for x should equal 5. It works when you know both N and x, but is this enough to solve for N? This is my best attempt so far. So if you are curious please respond with your own polynomial simplifications. Respond if you fill that I am serious and on the right path of solving the least common multiple.
  15. Reduced this polynomial: {(((((N^4 / x) + 2 * (N^2 * x^2) + x^5) / n^3) * x^3) / N} to ((N^4 / x^5 + 2 * N^2 / x^2 + x) * x^3) / (N4 / x^4) Sqrt{((N^4 / x^5 + 2 * N^2 / x^2 + x) * x^3) / (N4 / x^4)} =x Need some math help. I reduced the polynomial. However, the result does not seem any easier to solve. The black is the original the red is reduced. N is known. And x is to be solved. Can anyone solve this simplified polynomial?
