Hi,
Consider the simple problem
p lp min 1 1 0
i 1 d -1 1
n i 1 constraint
j 1 f
n j 1 variable
e o f
Standard, the variable is non-basic fixed at lower bound and the
constraint is basic. When I set the variable as basic and constraint as
non-basic, I get, when warming up the basis:
Assertion failed: k1 < k2
Error detected in file <path>/glpk-4.54/src/bflib/sgf.c at line 165
Is this expected? (I was expecting an error code signaling an invalid
basis at the worst.)
Best,
Erik
