It is often claimed that Evolutionary Algorithms are superior to other optimization techniques, in particular, in situations where not much is known about the objective function to be optimized. In contrast to that Wolpert and Macready (1997) proved that all optimization techniques have the same behavior — on aver age over all f : X → Y where X and Y are finite sets. This result is called No Free Lunch Theorem. Here different scenarios of optimization are presented. It is argued why the… Expand
Searching for a Practical Evidence of the No Free Lunch Theorems
TLDR
Several test functions for which Random Search performs better than all other considered algorithms have been evolved and show the effectiveness of the proposed evolutionary approach. Expand
On Classes of Functions for which No Free Lunch Results Hold
TLDR
The main result of this paper is proven that the fraction of subsets that are c.u.p. is negligibly small, which means that classes of objective functions resulting from important classes of real-world problems are likely not to be c. Expand
Arbitrary function optimisation with metaheuristics
TLDR
This work proposes an empirical framework, arbitrary function optimisation framework, that allows researchers to formulate conclusions independent of the benchmark problems that were actually addressed, as long as the context of the problem class is mentioned, and presents the first thorough empirical study on the no free lunch theorems. Expand
Optimization with randomized search heuristics - the (A)NFL theorem, realistic scenarios, and difficult functions
TLDR
An Almost No Free Lunch (ANFL) theorem shows that for each function which can be optimized efficiently by a search heuristic there can be constructed many related functions where the same heuristic is bad. Expand
A Fitness Function Elimination Theory For Blackbox Optimization And Problem Class Learning
The modern view of optimization is that optimization algorithms are not designed in a vacuum, but can make use of information regarding the broad class of objective functions from which a problemExpand

TLDR
It is proved that k-coloring problems respect such a notion of structure, for any k, which leads to the observation that the notion ofructure of optimization problems is missing in NFL use. Expand
When and why metaheuristics researchers can ignore “No Free Lunch” theorems
TLDR
An argument against a common paraphrase of NFL findings—that algorithms must be specialised to problem domains to do well—after problematising the usually undefined term “domain” is presented, which offers a novel view of the real meaning of NFL. Expand

Evolutionary algorithms (EAs) are randomized search strategies that have turned out to be efficient for somewhat different optimization problems. In order to understand the behavior of EAs, one isExpand
Continuous Lunches Are Free Plus the Design of Optimal Optimization Algorithms
TLDR
It is proved that the natural extension of NFL theorems, for the current formalization of probability, does not hold, but that a weaker form of NFL does hold, by stating the existence of non-trivial distributions of fitness leading to equal performances for all search heuristics. Expand
Free lunches on the discrete Lipschitz class
TLDR
It is concluded that there exist algorithms outperforming random search on the discrete Lipschitz class in both theoretical and practical aspects and indicates that the effectiveness of search heuristics may not be universal but still general in some broad sense. Expand
