Simple, Fair and Terminating Backtracking Monad Transformer.

This Haskell library provides an implementation of the MonadPlus type class that enumerates results of a non-deterministic computation by interleaving subcomputations in a way that has usually much better memory performance than other strategies with the same termination properties.

Simple, Fair and Terminating Backtracking Monad Transformer

This Haskell library provides an implementation of the MonadPlus type class that enumerates results of a non-deterministic computation by interleaving subcomputations in a way that has usually much better memory performance than other strategies with the same termination properties.

It also terminates in many cases where the fair conjunction and interleaving operators provided by LogicT fail to do so, allowing it to safely provide fairness by default.

This package aims to be a drop-in replacement for the unmaintained stream-monad package, in addition to providing much of the same functionality as the logict package.
