Initially I wanted to detect the index of an array where the value is different
of zero, you guys helped me suggested me the following command:
param index1 := min{k in SCHEDULES: values[k] != 0} k;
The problem arises because there are some cases where the whole array "values"
has zero values, and the min command does not work, a message error is shown:
"min{} over empty set; result undefined
MathProg model processing error"
and for these cases a value of index=1 will help me a lot.
Does anybody have some suggestions?
Thank you very much for your time
