PREPROBING

Presolve: Amount of probing to perform on binary variables during presolve. This is done by fixing a binary to each of its values in turn and analyzing the implications.

Integer

-1	Let the optimizer decide on the amount of probing.
0	Disabled.
+1	Light probing — only few implications will be examined.
+2	Full probing — all implications for all binaries will be examined.
+3	Full probing and repeat as long as the problem is significantly reduced.
