I think you should switch to the dual simplex method before
re-optimization.
Perfectly correct, because if the current basis is optimal, changing
bounds of variables leads to the dual feasibile basis. To enable the
dual simplex method one needs to set the control paramater LPX_K_DUAL.
Hi, Andrew and other guys,
I have 2 questions about LP with glpk.
1) How to deal with problems with constraint boundary disturbance quickly. For
example, originally I have L_ix_iU_i (i=1,...n), when I get the answer of x,
how can I get another answer with glpk quickly to L_i-ex_iU_i+e,where e
