fixmipentities

Purpose
Fix values of discrete entitites according to the current solution.
Synopsis
procedure fixmipentities
procedure fixmipentities(options:integer)
Argument
options 
Options sent to the library routine XPRSfixmipentities
Example
Solve the MIP problem, reload the problem after solving, fix discrete entities to their solution values, and finally solve the LP for the continous variables in order to be able to use getrange. 
minimize(obj)
fixmipentities
minimize(XPRS_LIN, obj)
writeln(getrange(XPRS_UPACT,x))
Further information
1. This procedure fixes the non-continuous variables to their value of the current solution. A call to this function is required when performing sensitivity analysis on MIP problems using getrange.
2. The first form of the procedure corresponds to fixmipentities(0).
