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
