Calculation of Euclidean distances

GAMS
1

Hello,

how can I calculate a euclidean distance in Gams?



d(i,j) = ((x(i)-x(j))^2+(y(i)-y(j))^2)^1/2 doesn’t work.

Gams won’t work with ^2.
Can somebody help me?

Greetings,
Paul

Hi Paul: Why is ^2 (**2) bringing you trouble ?

You are probably better off with d(i,j) = (power(x(i)-x(j),2)+power(y(i)-y(j),2))^(1/2)

Problem solved.

** instead of ^ works.
