Crash Ordering

Type

Integer

Range

{-1 .. 1}

Default

1

This option determines how CPLEX orders variables relative to the objective function when selecting an initial basis. Possible values are:

For LP primal simplex :

0: Ignore objective coefficients during crash

-1 or 1: Alternate ways of using objective coefficients

For LP dual simplex :

0 or -1: Aggressive starting basis

1: Default starting basis

For QP Primal :

-1: Slack basis

0: Ignore Q terms and use LP solver for crash

1: Ignore objective and use LP solver for crash

For QP Dual :

-1: Slack basis

0 or 1: Use Q terms for crash
