Hello,
Is it possible to express the function min according to a boolean variable?
For instance:
I have:
Set = {a,b,c,...} which represents the set of elements
par : is a parameter specified for each element
par[a]=10;
par[b]=10;
par[c]=15;
var : is a boolean variable
var (i,j) such as: i and j are in set and i!=j.
I would like to define a boolean variable for each element Y[i] (i in set) such
as Y[i] = 1 if:
for each element j in set (i != j) if var [i,j] = 1 then par[i]< par[j].
Y[i] = 0 if there exists at least one element for which var [i,j] = 1 and
par[j]< par[i].
Thank you in advance_______________________________________________
