Q: Is it possible too loop over elements of alist and use the values as indices?

Example:

A[0..29] = inFile.readInt();

x <- list(30);

// some constraints for x

result <- sum[i in x](A[i]);

maximize result;

A:Yes, you can do this using

variadic operators.

In your example, you canwrite:

A[0..29] = inFile.readInt();

x <- list(30);

// some constraints for x

result <- sum(x, i => A[i]);

maximize result;

A good use case of

lambda functions can be

found for instance

in the CVRPproblem
