## Hi Konstantinos

What is the probability that the sum of three random numbers is 1? My guess is zero. This means that you will not solve any model instance, at least not with this probability distribution.

Hi Konstantinos

You should use i not ii in the loop.

Hello,

I have three weights let’s say: w1=U[0,1], w2=U[0,1], w3=U[0,1].

I want to solve a model only if the sum of the three weights are equal to 1 or w1+w2+w3=1.

I did the following:

set i/1*100/;

.

.

.

w1(i)=uniform(0,1);

w2(i)=uniform(0,1);

w3(i)=uniform(0,1);

.

.

.

alias(i,ii);

loop(ii,

if( w1(i)+w2(i)+w3(i)=1,

Solve MODEL MAX OBJ;

);

);

But after the first iteration it stops.

Can you please help me?
