In the model, do:
set indexes;
param values{indexes} ;
param index := min{k in indexes: values[k] != 0} k;
display index; # displays: index = 5
and in the data section, do:
param : indexes : values :=
1 0
2 0
3 0

Hi
I need to pre-process some data before an optimization problem begins.
I'm doing the following:
If I have the following array of parameters:
param values = [0 0 0 0 8 9 0 0]
I would like to have in one parameter the index k where the first element of
the array "values" is different of zero, i.e.
param index := 5 due to values[5] != 0
could you help me with this.
Thank you in advance
Victor
