BEB was no longer able to compete with OPPS-DS and was even beaten by BAMCP and BFS3 in the last experiment. -Greedy was still a decent choice except in the first experiment. As observed in the accurate case, Soft-max was very bad in every case. In Fig 12, if we take a look at the top-right point, we can see OPPS-DS is the best choice in the second and third experiment. BEB, SBOSS and -Greedy share the first place with OPPS-DS in the first one. If we place our offline-time bound right under OPPS-DS minimal offline time cost, we can see how the top is affected from left to right: GC: (Random), (Random, SBOSS), (SBOSS), (BEB, SBOSS, -Greedy), (BEB, BFS3, SBOSS, -Greedy), GDL: (Random), (Random, SBOSS), (BAMCP, Random, SBOSS), (BEB, SBOSS, -Greedy), (BEB, BFS3, SBOSS, -Greedy), (BAMCP, BEB, BFS3, SBOSS, -Greedy), Grid: (Random), (Random, SBOSS), (BAMCP, BEB, BFS3, Random, SBOSS), (-Greedy). SBOSS is again the first algorithm to appear in the rankings. -Greedy is the only one which could reach the top in every case, even when facing BAMCP and BFS3 fed with high JNJ-54781532 side effects online computation cost. BEB no longer appears to be undeniably better than the others. Besides, the two first experiments show that most algorithms obtained similar results, except for BAMCP which does not appear on the top in the first experiment. In the last experiment, -Greedy succeeded to beat all other algorithms.

In the accurate case, OPPS-DS was always among the best algorithms, at the cost of some offline computation time.
