A general-purpose open-source solver suite used to actually solve the formal
problems of cutting & packing (classified as a tool in v1, grade C — project /
vendor documentation). The 0/1 Knapsack Problem is
handled by OR-Tools' KnapsackSolver, and
integer linear programming formulations by
its CP-SAT / MIP solvers. It is not specialized for geometric problems such as
nesting.
