89. DBGCLD and 90. DBGWRM

These two parameters give you control over the linear solver that is used by the DEBUG command for model debugging.  The available choices are:

DBGCLD/DBGWRM

Debug Linear Solver

0

Solver Decides — LINGO selects the solver it believes is the most appropriate,

1

Primal — the primal simplex solver will be used,

2

Dual — the dual simplex solver will be used, and

3

Barrier — the barrier solver will be used (requires a barrier solver license).

DBGCLD selects the solver for cold starts (starting without an existing basis in memory) and DBGWRM selects the solver for warm starts (restarting from an existing basis).

LINGO defaults to Solver Decides for both the cold and warm debug solver.
