A Discrete Particle Swarm Optimizer for the Design of Cryptographic Boolean Functions

no code implementations9 Jan 2024 Luca Mariot, Alberto Leporati, Luca Manzoni

A Particle Swarm Optimizer for the search of balanced Boolean functions with good cryptographic properties is proposed in this paper.

Local Search, Semantics, and Genetic Programming: a Global Analysis

no code implementations26 May 2023 Fabio Anselmi, Mauro Castelli, Alberto D'Onofrio, Luca Manzoni, Luca Mariot, Martina Saletta

In recent years, a new mutation operator, Geometric Semantic Mutation with Local Search (GSM-LS), has been proposed to include a local search step in the mutation process based on the idea that performing a linear regression during the mutation can allow for a faster convergence to good-quality solutions.

Evolutionary Strategies for the Design of Binary Linear Codes

no code implementations21 Nov 2022 Claude Carlet, Luca Mariot, Luca Manzoni, Stjepan Picek

The design of binary error-correcting codes is a challenging optimization problem with several applications in telecommunications and storage, which has also been addressed with metaheuristic techniques and evolutionary algorithms.

The Effect of Multi-Generational Selection in Geometric Semantic Genetic Programming

no code implementations5 May 2022 Mauro Castelli, Luca Manzoni, Luca Mariot, Giuliamaria Menara, Gloria Pietropolli

Among the evolutionary methods, one that is quite prominent is Genetic Programming, and, in recent years, a variant called Geometric Semantic Genetic Programming (GSGP) has shown to be successfully applicable to many real-world problems.

Salp Swarm Optimization: a Critical Review

1 code implementation3 Jun 2021 Mauro Castelli, Luca Manzoni, Luca Mariot, Marco S. Nobile, Andrea Tangherloni

In the crowded environment of bio-inspired population-based metaheuristics, the Salp Swarm Optimization (SSO) algorithm recently appeared and immediately gained a lot of momentum.

Tip the Balance: Improving Exploration of Balanced Crossover Operators by Adaptive Bias

no code implementations23 Apr 2020 Luca Manzoni, Luca Mariot, Eva Tuba

Experiments show that improving the exploration of the search space with this adaptive bias strategy is beneficial for the GA performances in terms of the number of optimal solutions found for the balanced nonlinear Boolean functions problem.

CoInGP: Convolutional Inpainting with Genetic Programming

1 code implementation23 Apr 2020 Domagoj Jakobovic, Luca Manzoni, Luca Mariot, Stjepan Picek, Mauro Castelli

In the second experiment, we train a GP convolutional predictor on two degraded images, removing around 20% of their pixels.

Balanced Crossover Operators in Genetic Algorithms
