Ready-made solver configurations to pass to solve_scenario() as
solver = solver_options[["<name>"]]. The name encodes the route and the
algorithm: a bare backend (glpk), pyomo_* for the Python route, mm_*
for the multimod matrix route, and a _barrier suffix for the interior-point
method rather than simplex. The matrix presets name the matrix writer, the
solver and the place: mm_cuopt_wsl (cuOpt on a local GPU through WSL),
mm_cuopt_cloud (cuOpt on a rented GPU), pyomo_cuopt_cloud (a Pyomo-written
matrix on a rented GPU).
Details
These entries are data only – selecting one does not check that the solver
is installed. The former names mmcloud, mmcloud_crossover,
mmcloud_pyomo and mmcloud_pyomo_crossover remain as entries that stop a
solve and name their replacement.
