Target Constraints and Reconfiguration
Look up syntax, contracts, layouts, algorithms, and exact behavior.
The target is constrained so the search problem remains valid and the controls remain usable. Its x coordinate must stay to the right of the launcher by a fixed minimum, its radius must fit inside the stage, and it must avoid the wind panel region so the draggable target does not overlap UI instrumentation.
control change or drag | v copy ranked genomes from previous summary | v resize population to new populationSize | v clamp target to legal bounds | v evaluate immediately under new config | v reset solved streak
Population resizing is rank-preserving. If the population shrinks, the highest-ranked genomes survive. If it grows, new random genomes are appended. That gives configuration changes continuity without pretending old convergence statistics still apply.
