pReproduction: Premature Convergence & Stagnation<br />

:: Two (strongly related) important issues in the evolution process<br />

population diversity,<br />

selective pressure.<br />

:: Premature convergence – a premature loss <strong>of</strong> diversity in the population with the search<br />

converging to a sub-optimal solution.<br />

early stages <strong>of</strong> the evolution search process.<br />

:: Stagnation – ineffective search due to a weak selective pressure.<br />

later stages <strong>of</strong> the evolution search process.<br />
