I am using a model coded in GMPL.
The model has a large two-dimensional array of x variables, one
dimension has literal indices that are defined in a set in the data
segment (example is B1)
This model is running and solving so far.
However, I need to initialize a very few of the x variables because of
boundary conditions.
Statement in the model section is similar to
s.t. x[B1,21]=1;
This cannot be done because B1 is not yet defined (from the data section).
How can I initialize some of the variables in the data section, or what
is the sequence of actions that can achieve this.
Thanks.
