As you continue your journey in mathematical optimization, remember that every modern solver owes a debt to the algebraic paradigm that GAMS 23.5.1 perfected.
: Models can be moved between different platforms (e.g., Windows, Linux) without changing the underlying code. Version 23.5.1 Specifics
Scalar f "freight cost" / 90 /; Parameter c(i,j) "transport cost"; c(i,j) = f * d(i,j) / 1000;
Variables x(i,j) "shipment quantities" z "total cost" ;
