Web25. okt 2024 · We present Scrybe, an example-based synthesis tool for a statically-typed functional programming language, which combines top-down deductive reasoning in the style of λ^2 with Smyth-style live bidirectional evaluation. During synthesis, example constraints are propagated through sketches to prune and guide the search. WebIn traditional top-down synthesis, a branch of search can be safely pruned by proving that a program satisfying the specification cannot exist in that branch. In CTS, we can safely prune a branch of search if we can prove that it cannot contain the optimal abstraction.
