Theory of Games and Economic Behaviour is the classic work upon which modern-day game theory is based. The common elements of economic behaviour and such factors as strategy in games are presented, and the interrelated concepts are analysed around the more or less central problem of utility. John von Neumann and Oskar Morgenstern are two gifted mathematicians that by working together succeeded in writing and estimating amazing and breakthrough formulas that are used in solving of problems till our days. Von Neumann, as a scientist, affected the whole world of computer science and mathematics simultaneously and he, literally allowed the future generations to develop and study the potential of computers finally obtaining that PC(Personal Computer) that we all are using today.
