XSLP_MIPRELAXSTEPBOUNDS

Description
Bitmap describing the step-bound relaxation strategy during MISLP
Type
Integer
Values
Bit
Meaning
 
0 
Relax step bounds on structural SLP variables which are not in coefficients.
1 
Relax step bounds on all structural SLP variables.
2 
Relax step bounds on SLP variables appearing only in coefficients.
3 
Relax step bounds on SLP variables appearing in coefficients.
Default value
15 (relax all types)
Note
At any node (including the initial and optimal nodes) it is possible to relax the step bounds of classes of variables so that the variables themselves are completely free to change. This may help with finding a global optimum, but it may also increase the solution time, because more SLP iterations are necessary at each node to obtain a converged solution.
