Creating a Model in Slot Gams
Creating a model in Slot Gams involves several steps. Here’s a brief overview:
-
Define the decision variables: These are the variables that you want to optimize.
-
Specify the objective function: This is the function that you want to maximize or minimize.
-
Define the constraints: These are the conditions that the solution must satisfy.
-
Solve the model: Use a solver to find the optimal solution.
Here’s an example of a simple linear programming model in GAMS:
sets i /13/; parameters a(i) /1 1, 2 2, 3 3/; variables x(i) /13/; equations obj .. z =e= sum((i), a(i)x(i)); cons1 .. sum((i), x(i)) =l= 5; cons2 .. sum((i), x(i)) =g= 2; model m1 /all/;solve m1 using lp minimizing z;display x.l;Slot Gams in Practice
