Executive Summary
This report details a simulation-based framework for studying minefield search behavior, adapting an existing simulation environment for mine warfare analysis. It compares structured and learning-based search configurations, specifically Q-table methods, within a selected challenging minefield regime. The study highlights that while learning-based approaches can capture useful patterns, effective mission performance requires careful reward design and state representation.

This report documents the development and use of a simulation-based framework for study-ing minefield search behavior under controlled conditions. The work focused on adapting a simulation environment for mine warfare analysis, conducting a limited screening study to identify a representative challenge regime, and comparing structured and learning-based search configurations within that regime.
- Tabular Q-learning showed potential for learning useful search patterns but did not guarantee mission success without careful reward design and state representation.

The results showed that tabular Q-learning in this setting was capable of capturing some useful structure, but that learned motion alone did not guarantee mission-effective per-formance. The study reinforced several practical lessons. Regime selection matters. Mine neutralization must remain the dominant reward objective. Exploration is most useful as
- The study provides practical lessons on regime selection, the importance of mine neutralization as a primary objective, and the role of exploration in learning-based minefield search.

The report also delivered a practical comparison between a structured lawnmower baseline and several Q-table operating modes within the selected regime. That comparison showed that learning-based search in this setting was neither trivial nor uniformly successful. At the same time, it was still informative.
Strategic Relevance
The research directly contributes to enhancing mine warfare capabilities, a critical aspect of naval operations and sea control. Improving mine countermeasures through AI-driven search strategies can reduce risks to naval assets and personnel, and accelerate clearance operations in contested maritime environments.
