fixglobal


Purpose
Fix values of global entitites according to the current solution.
Synopsis
procedure fixglobal
procedure fixglobal(ifrnd:boolean)
Argument
ifrnd 
if true, integer solution values are rounded
Example
Solve the MIP problem, reload the problem after solving, fix global entities to their solution values, and finally solve the LP for the continous variables in order to be able to use getrange.
minimize(obj)   
fixglobal                 
minimize(XPRS_TOP+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 fixglobal(false).
