Sum Operator (Solver Foundation)

Evaluates an expression for each possible combination of values of some iterator variables, and returns the sum of the results.

Sum[iters…, expr]

Example

Sum[{p, Products}, x[p]]

Sum[{p, Products}, {s, Sources}, x[p, s]]

Sum[{i, 5}, x[i]]

Sum uses the same iterator forms as Foreach. If no iterators are specified, Sum just evaluates expr.
