<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN-US" style="font-size:11.0pt">Hi,<br>
<br>
you could try to crank up how much primal heuristics are run. At least <br>
for that small example, the dual bound seems to be best possible from <br>
the beginning one and it only took a while to find a feasible solution <br>
with same objective value.<br>
The primal heuristic that found the solution with objective function <br>
value 4 was nlpdiving, which makes some sense. So changing <br>
heuristics/nlpdiving/freq and other parameters of this heuristic may <br>
help to make it run more often or more extensively.<br>
You can also make all primal heuristics run more extensively by setting <br>
the emphasis for heuristics to aggressive (doing this through AMPL may <br>
be a bit difficult; maybe just open a SCIP shell from a SCIP binary, <br>
type set heuristics emphasis aggr <br>

and copy the parameter changes).<br>
<br>
Since the only nonlinearity are products of binary and bounded <br>
continuous variable, if I get that right, then you could also try <br>
whether letting SCIP reformulate the problem into a MIP in presolve <br>
(constraints/quadratic/binreformbinaryonly = FALSE, maybe try also <br>
constraints/quadratic/replacebinaryprod = 1) helps.<br>
