A question about IntVarArrays: I have a large CSP that I have coded to be constructed incrementally as the search proceeds to reduce memory usage. To simplify, lets say that I have an array of N variables for some large N, and each one is constrained by some relationship with its neighbours. Rather than create all N variables and N-1 constraints immediately, I create and constrain variables incrementally once the previous variable has been assigned. (My real situation is actually more complex than this, but my question remains the same).
Currently, I create an IntVarArray as: vars = IntVarArray(space, N); and then incrementally create variables as: vars[t] = IntVar(space, domainSet); My question is: does this actually save memory? I assume that creating the array created N 'uninitialised' IntVars. Are these variables significantly smaller than initialised IntVars? Or is this a false saving? Would I be better to create a smaller IntVarArray and replace it with an incrementally longer one as variables are created?
