Def evaluationFunction(self, currentGameState, action): """ Design a better evaluation function here. The evaluation function takes in the current and proposed successor GameStates (pacman. py) and returns a number, where higher numbers are better.

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.
