Dear all,
I am running an optimization problem (multi-period DC-optimal power flow). And when using set_normalized_rhs
function to modify the constant term on the right-hand-side of the concerned constraints and re-optimizing, the number of iterations (and the computational time to solve the optimization) increases directly starting from the second optimization. From the second optimization, the number of iterations is relatively constant but much greater than the first one, i.e. the first optimization is solved in 7 seconds (+/- 30 iterations) and all the following optimizations are solved in 200 seconds approximately (+/- 150 000 iterations).
I cannot explain this, if anyone has faced the same problem or has an idea to solve this problem, please let me know.
