Subject: creating subsets from other sets with numeric clauses
Date: Mon, 3 Mar 2014 03:37:10 +0000
Hi,
I am trying the create a subset based on content of a data set in GMPL.
Using the assign,mod in examples directory –
param c{i in I, j in J}, >= 0;
/* cost of allocating task j to agent i */
param d {(i,j) in I cross J: c[i,j]=12} := c[i,j];
display d;
set E := {(i,j) in I cross J: d[i,j]>0};
display E;
getting;
Display statement at line 33
d[1,4] = 12
d[2,1] = 12
d[4,5] = 12
d[5,7] = 12
Display statement at line 35
assign.mod:35: d[1,1] out of domain
MathProg model processing error
Parameter d is created correctly, but set E is not! What is the correct
way of creating such subsets based on parameter clause(s)?
thanks
