Hi all,
I'm trying to specify fixed values to some variables in an array using =
expression (see 4.3 Variable statement in GMPL Reference). Something
like this:
set MySet;
set MySubset within MySet;
var X {i in MySet} = if i in MySubset then 0 else binary;
or, similarly:
var X {i

If I keep the presolver on, the basis information from the previous
solve is lost and the 2-phase primal algorithm kicks off from scratch
(instead of the dual simplex using the previous basis). If I turn the
presolver off, I know my problem is bigger than it needs to be, but
the dual simplex
