About This App

Compatibility: This evolver uses the same rules as your Recursive Production Grammar: LHS -> RHS with | alternates, terminals in "quotes", uppercase nonterminals, epsilon {}, newline token {br}, and per-alternative weight {p=0.42}.

Workflow: Click Evolve to optimize weights; a fresh stanza is generated and the poem grows via duplicate / erase / loop-back operations.
