An Unconditional Lower Bound for the Active-Set Method in Almost-Linear Programming
Eleon Bach, Yann Disser, Sophie Huiberts +1
We prove that, for every fixed , the active-set method requires exponentially many iterations in the worst case to maximize a convex objective of the form $(x_1)^{1+ε}+\…

An unconditional lower bound for the active-set method on the hypercube
Yann Disser, Nils Mosis
The existence of a polynomial-time pivot rule for the simplex method is a fundamental open question in optimization. While many super-polynomial lower bounds exist for individual o…

A unified worst case for classical simplex and policy iteration pivot rules
Yann Disser, Nils Mosis
We construct a family of Markov decision processes for which the policy iteration algorithm needs an exponential number of improving switches with Dantzig's rule, with Bland's rule…
