Machine learning was coined by IBM employee, Arthur Samuel, in 1959. The start of machine learning actually began with a game of checkers where Robert Nealey, a checkers master, was beaten by an IBM computer. Over the last 60 years, machine learning has become a lot more sophisticated and ...
For example, the expression(A∧B)∨(A∧¬B)is satisfiable, with one valid assignment being A=B=True. Note that in it's standard form, SAT is a decision problem: it suffices to decide whether such an assignment exists, we don't have to find it. 例如,表达式(A∧B)∨(A∧¬B)是...
Up until Onsager’s exact solution of the model, it was assumed that the critical exponents were given by the mean field approximation. Onsager’s solution allowed the mistake to be caught [36]. A few years later, when Maddox in 1952 presented his claim of a solution to the 3D model, ...
