Description | Primal simplex: allows fine tuning the variable selection in the primal simplex solver.
Type | Integer
Topic areas | LP, Simplex, Bit-vector
Values |
Bit | Meaning
0 | Use aggressive dj scaling.
1 | Conventional dj scaling.
2 | Use reluctant switching back to partial pricing.
3 | Use dynamic switching between cheap and expensive pricing strategies.
4 | Keep solving even after potential cycling is detected.
Default value | -1
Note | If both bits 0 and 1 are both set or unset then the dj scaling strategy is determined automatically. See Section Bit-vector controls for bit-vector controls.
Affects routines | XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
