Defining CPLEX solution method¶
CPLEX has different solution algorithms that can be used to solve a LP problem. It is possible to choose the algorithm by giving the command:
set method /<option>The following options are allowed:
| Option | Comment |
|---|---|
| primal | Primal simplex method |
| dual | Dual simplex method |
| baropt | Barrier solver |
| hybbaropt | Hybrid barrier solver |
| netprimal | Network primal solver with additional constrains |
| netdual | Network dual solver with additional constrains |
The default solver is dual simplex.
When using MIP modelling, a branch and bound algorithm will automatically be used as this is the only valid alternative.
