[gecode-users] Float values and element constraint

[Arshad Khan]

Hello All,

I am a Gecode novice and seeking your expert help on one of the issue that
I am facing when using float values.

In the example warehouse.cpp, the supply cost from a warehouse to a store
is defined using an int value matrix (c_supply). This matrix is later used
in one of the constraint that computes the cost. Now I want to use a cost
matrix of float values. However, the constraint uses an 'element'
constraint to compute the cost which is not defined for float values. How
can I convert the constraint to use float values? Any help is greatly
appreciated.

For your reference, the relevant code from the example is follows:

// Compute cost for each warehouse
for (int s=0; s<n_stores; s++) {
   IntArgs c(n_warehouses, c_supply[s]);
   c_store[s] = expr(*this, element(c, supplier[s]));
}

(What I want is to have a FloatValArgs type for c.)

Thanks and Regards
Arshad
