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
