### Re: Summation with parameter

Hello again, I worked on the code again. And I noticed while checking all indices in a constraint; which is j and s; the constraint generates denominator as 0. Therefore, the code gives error of division by zero . To get rid of this problem, I should write the denominator part not equal to zero as a...

### Re: Summation with parameter

Hi Renger, I sent my code to you in DM. Could you check it? I tried different index values (for k=1 and k=3) to check the generated constraints but they gave different results. Therefore I could not understand the problem in code and constraints. And also I can not understand the division by zero er...

### Re: Summation with parameter

Hi Renger, Thanks a lot for your answer. The model did not give any syntax error after your correction. But now, the code exits with code 3 which is error for division by 0. However, I checked whole code, the paranthesis, defined parameters and their values many times. Any of them should not cause s...

### Re: Summation with parameter

Hi, Thanks for your answer. I will use it in another part of my code. In my problem: Indexes: s intervals for each criteria (1,2,..,pp(j)) --> [I write this part as " s /1*pp(j)/ " it gives error 764 ] j number of criteria k training data set elements Parameters: p(j) number of breakpoints pp(j) num...

Hello everybody, I am trying to write the code of UTADIS method. In this code I could not write a summation function. In the function I have an index s for the summation. However the upper bound of the summation depends on a parameter which is r(j,k). And, I sum w(j,s). Related mathematical formulat...
