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. Web8. jan 2024 · Top-down synthesis incrementally builds up a sketch, a program that may contain holes (denoted by \CIRCLE _ {} ). Holes may be annotated with constraints, e.g. type constraints. During synthesis, holes are filled with new sketches (possibly containing more holes) until no holes are left.
