IGOR2 - an analytical inductive functional programming system: tool demo

The analytical inductive programming system IGOR II is an implemented prototype for constructing recursive functional programs from few non-recursive, possibly non-ground example equations describing a subset of the input/output (I/O) behaviour of a function. Starting from an initial, overly general program hypothesis, stepwise several refinement operators are applied which compute successor hypotheses. Organised as an uniformed-cost search, the hypothesis with the lowest costs is developed and replaced by its successors until the best does not contain any unbound variables.
