Integer Natural Evolution Strategies

The DG distribution belongs to the exponential family, and it is established that DG-based step-size adaptation arises directly from the statistical structure of the mutation distribution, rather than as a discrete analog of continuous ES mechanisms.

Reliable Virtual Sensing: A Multi-Domain Benchmark for Robustness Under Sensor Failures

It is argued that real-world deployment demands robustness and introduced MuViS-C, the first multi-domain benchmark of robustness against common sensor failures in learning-based virtual sensing, which covers ten sensor failure modes, from subtle drifts to catastrophic signal dropouts, at multiple severities.

Large language models and evolutionary computation: A critical review of bidirectional interaction, automated algorithm design, and co-adaptive systems

The bidirectional interaction between large Language Models and Evolutionary Computation is reviewed and how their complementary strengths can be leveraged in hybrid intelligent systems is examined.

Beyond Scalar Fitness: Behavioural Feedback for LLM-Driven Metaheuristic Evolution

It is found that neutral framing of behavioural features, reporting the feature value without prescriptive advice, consistently outperforms the prescriptive variants, and that prescriptive feedback steers the median feature value in the advised direction in only 37% of cases despite empirically grounded advice.

Evolving Executable Pipeline Programs for AutoML with Language Models

This work presents LACE, an AutoML framework that instead searches over complete executable pipeline programs: an evolutionary loop maintains a population of scikit-learn-compatible Python classes, and a large language model acts as the variation operator.
