Finding Near-Optimal Portfolios With Quality-Diversity

no code implementations25 Feb 2024 Bruno Gašperov, Marko Đurasević, Domagoj Jakobovic

In this paper, we present a novel approach for finding a diverse set of such portfolios based on quality-diversity (QD) optimization.

A Systematic Evaluation of Evolving Highly Nonlinear Boolean Functions in Odd Sizes

no code implementations15 Feb 2024 Claude Carlet, Marko Ðurasevic, Domagoj Jakobovic, Stjepan Picek, Luca Mariot

In the last 30 years, evolutionary algorithms have been shown to be a strong option for evolving Boolean functions in different sizes and with different properties.

A New Angle: On Evolving Rotation Symmetric Boolean Functions

no code implementations20 Nov 2023 Claude Carlet, Marko Ðurasevic, Bruno Gašperov, Domagoj Jakobovic, Luca Mariot, Stjepan Picek

Rotation symmetric Boolean functions represent an interesting class of Boolean functions as they are relatively rare compared to general Boolean functions.

Digging Deeper: Operator Analysis for Optimizing Nonlinearity of Boolean Functions

no code implementations12 Feb 2023 Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Stjepan Picek

By observing the range of possible changes an operator can provide, as well as relative probabilities of specific transitions in the objective space, one can use this information to design a more effective combination of genetic operators.

On the Evolution of Boomerang Uniformity in Cryptographic S-boxes

no code implementations9 Dec 2022 Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Sihem Mesnager, Stjepan Picek

One example of such a property is called boomerang uniformity, which helps to be resilient against boomerang attacks.

Evolving Constructions for Balanced, Highly Nonlinear Boolean Functions

no code implementations17 Feb 2022 Claude Carlet, Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Stjepan Picek

Finding balanced, highly nonlinear Boolean functions is a difficult problem where it is not known what nonlinearity values are possible to be reached in general.

Evolutionary Construction of Perfectly Balanced Boolean Functions

no code implementations16 Feb 2022 Luca Mariot, Stjepan Picek, Domagoj Jakobovic, Marko Djurasevic, Alberto Leporati

Finding Boolean functions suitable for cryptographic primitives is a complex combinatorial optimization problem, since they must satisfy several properties to resist cryptanalytic attacks, and the space is very large, which grows super exponentially with the number of input variables.

Modeling Strong Physically Unclonable Functions with Metaheuristics

no code implementations16 Feb 2022 Carlos Coello Coello, Marko Djurasevic, Domagoj Jakobovic, Luca Mariot, Stjepan Picek

While there is no reason to doubt the performance of CMA-ES, the lack of comparison with different metaheuristics and results for the challenge-response pair-based attack leaves open questions if there are better-suited metaheuristics for the problem.

Building the Building Blocks: From Simplification to Winning Trees in Genetic Programming

no code implementations29 Sep 2021 Lucija Planinić, Marko Đurasević, Stjepan Picek, Domagoj Jakobovic

The winning trees can be used to initialize the population for the new GP run and result in improved convergence and fitness, provided some conditions on the size of solutions and winning trees are fulfilled.
