(12-23-2023 04:44 AM)Albert Chan Wrote:  Problem is simplex() first CASE ... END, to parse user input.
Removing first CASE ... END solved crashing issue.
Thanks for catching the source of the crash/reset, I implemented the change and uploaded new files.

(12-23-2023 04:44 AM)Albert Chan Wrote:  Also, simplex() solved equality constraints using art variables, simplex_le() by variable eliminations.

test01() example:

> simplex([[1,2,0,1,20],[2,1,1,0,10],[-1,4,-2,3,40],[1,4,3,2,0]],-3)
.
.
.
> simplex_le([[1,2,0,1,20],[2,1,1,0,10],[-1,4,-2,3,40],[1,4,3,2,0]],-3)

Is simplex_le able to solve test14? It is problem 2d in section 6.3 of the referenced textbook.

> simplex([[1,-1,0,12],[0,2,3,28],[2,-4,1,0]],2,[1,2,3])
> [28, ... , trn([14,2,8,...])]

> simplex_le([[1,-1,0,12],[0,2,3,28],[2,-4,1,0]],2,[1,2,3])
> infinte loop
