SPMTHD Setting

SP Solver Method

0

Solver Decides — LINGO decides the most appropriate method for solving the SP model

1

Deterministic Equivalent — LINGO generates and directly solves the deterministic equivalent (DE) of the SP model

2

Nested Benders Decomposition — The DE for realistic SP models can get to be quite large, in that the core model is replicated once for every scenario.  Fortunately, the DE displays strong block-angular structure, which makes it adaptable to decomposition techniques, such as nested Bender decomposition (NBD).  Note that the model must be entirely linear to successfully use the NBD option.
