Dynamic Initial Weight Assignment for MaxSAT
The Maximum Satisfiability (Maximum Satisfiability (MaxSAT)) approach is the choice, and perhaps the only one, to deal with most real-world problems as most of them are unsatisfiable.

Optimal analog wavelet bases construction using hybrid optimization algorithm [PDF]
An approach for the construction of optimal analog wavelet bases is presented. First, the definition of an analog wavelet is given. Based on the definition and the least-squares error criterion, a general framework for designing optimal analog wavelet ...

NILS: a Neutrality-based Iterated Local Search and its application to Flowshop Scheduling [PDF]
This paper presents a new methodology that exploits specific characteristics from the fitness landscape. In particular, we are interested in the property of neutrality, that deals with the fact that the same fitness value is assigned to numerous ...

Multi-agent collaborative search : an agent-based memetic multi-objective optimization algorithm applied to space trajectory design [PDF]
This article presents an algorithm for multi-objective optimization that blends together a number of heuristics. A population of agents combines heuristics that aim at exploring the search space both globally and in a neighbourhood of each agent.

Efficient Local Search for Pseudo Boolean Optimization
Pseudo-Boolean Optimization (PBO) can be used to model many combinatorial optimization problems. PBO instances encoded from real-world applications are often large and difficult to solve; in many cases, close-to-optimal solutions are useful and can be found reasonably efficiently, using incomplete algorithms.

An improved particle swarm optimization combined with double-chaos search
Particle swarm optimization (PSO) has been successfully applied to various complex optimization problems due to its simplicity and efficiency. However, the update strategy of the standard PSO algorithm is to learn from the global best particle, making it

Local policy search with Bayesian optimization
Reinforcement learning (RL) aims to find an optimal policy by interaction with an environment. Consequently, learning complex behavior requires a vast number of samples, which can be prohibitive in practice. Nevertheless, instead of systematically reasoning and actively choosing informative samples, policy gradients for local search are often obtained ...
