Let m≥1 and n≥1 be natural numbers, let p be a discrete probability mass function on Euclidean space Rm, and put S={x∈Rm:p(x)>0}. Let a=(a1,…,an) be a family of points of Rm (the moves) and let w=(w1,…,wn) be a point of Rn (the weights). Differences of points of Rm are those of Difference, Dot Product, and Orthogonality in Rn, and sums over 1≤j≤n are the finite sums of R.
The move score of p for the moves a and weights w is the function ρp,a,w:S→R,
ρp,a,w(x)=j=1∑nwj(1−p(x)p(x−aj)).
