Hi,
in OPL have a look in the IloCplex OPL object at
readMIPStarts
{void} readMIPStarts(name)
Reads the MST file denoted by name
and copies the MIP start information into the invoking IloCplex
object. The parameter AdvInd
must be turned on (its default is 1 (one)) in order for the MIP start information to be used with a subsequent MIP optimization.
and
writeMIPStarts
{void} writeMIPStarts(name, first, nb)
Writes MIP start information to the file denoted by name
. The designated MIP starts begin with the one designated by the index first
and continue to the specified number nb
of members. All MIP starts will be written if the first
and nb
arguments are omitted. The single MIP start designated by first
will be written if the num
argument is omitted.
regards
