RE: Simplex Algorithm
(12-24-2023 07:32 PM)ftneek Wrote:  Your first for loop seems to iterate over all x[I] (from 1 to len(x[1])), we only need to check the indices from the integers list, anything else does not matter if it is integer or not.

It was simply simplex_le original code, nested with b loop to handle possibly 2 edges.

1st b loop select column of x = 1 .. len(x[1]) = 1 .. (1 or 2)
2nd I loop select rows from integer list z, *not* all rows of x

Quote:break statement is nested inside a while and 2 for loops, so you may need to use break 3.
Or you are checking I>len(z) twice, should the second one be b>len(z)?

I mean to break out from b loop and WHILE loop.

But, with break n bug, this does not work.
It does not matter if you change 2 to 3, or even break 99
Code:
 WHILE len(x:=a[0]) DO  // Gomory's plane cutting algorithm
  FOR b FROM 1 to len(x[1]) DO
   FOR I FROM 1 to len(z) DO
    IF type(x[z[I]][b])!=DOM_INT THEN break END
   END;
   IF I>len(z) THEN break 2 END // 2 get ignored!
  END;
