define random parameter

GAMS
1

Hi

I have a question…!

How can I define a parameter h(i,l) in format of table randomly which includes two arrays 0 or 1 such that number of arrays 1 for each index i are equal m(i) . Note that m(i) is random parameter too!

h(i,p) is random parameter
m(i) is random parameter
the number of 1 in each row of table related to index i is equal m(i) exactly


I will be grateful to you if you answer my question

regards,

Dear Saba

I hope this help you.

set i /i1*i10/;

Set p /p1*p5/;


Parameter h(i,p);


scalar row /0/;

scalar coulmn /0/;

scalar loopcheck /1/;

parameter m(i);


loop(i,

\

  • Random values for m(i)

m(i)=ceil(uniform(0,card(p)));

loopcheck=0;

row=m(i);


while((loopcheck ne row) and (loopcheck lt card(p)),

\

  • Those columns that randomly should set to 1

coulmn= ceil(uniform(0,card(p)));

h(i,p)$(ord(p)=coulmn)=1;

loopcheck=sum(p,h(i,p)););


);


Display m,h;





Regards;
