TRUE if v and w are strategically equivalent, FALSE otherwise. If parameters=TRUE, whenever v and w are strategically equivalent, the function also returns k (a positive integer) and a (the characteristic function of an additive game, as a vector in binary order if binary=TRUE and in lexicographic order otherwise) such that \(\code{v} = \code{k} \code{w} + \code{a}\).
Arguments
v
A characteristic function, as a vector.
w
A characteristic function, as a vector.
binary
A logical value. By default, binary=FALSE. Should be set to TRUE if v and w are introduced in binary order instead of lexicographic order.
parameters
A logical value. By default, parameters=FALSE.
Details
Games \(v\in G^N\) and \(w\in G^N\) are strategically equivalent if there exist \(k>0\) and an additive game \(a\in G^N\) such that \(v(S)=k w(S)+a(S)\) for all \(S\in 2^N\).
