Abstract: The pursuit evasion game (PEG) is a natural phenomenon with implications for civilian and military applications. Researchers have developed methods to analyse PEG dynamics under various bio-inspired strategies, providing valuable insights into possible applications. Studies assume constant speeds for both the pursuer and evader, but this can result in less agile pursuit. This paper explores the trade-off between higher speed and less agility when the evader increases speed as the pursuer approaches. By simulating PEG trajectories, nine combinations of bio-inspired pursuer-evader strategies were tested using computer simulations. Results showed that a higher average speed may delay the evader's capture or even result in their escape in some instances. However, computer simulations indicate a mixed outcome for evader escape performance in cases of sudden turns and non-reactive evader strategies. The paper's results contrast existing results that rely solely on numerical computation of PEG outcomes under varying evader speeds.
