パッケージ: libghc-binary-search-dev (2.0.0-2)

Binary and exponential searches

__Introduction__

This package provides varieties of binary search functions. c.f. "Numeric.Search" for the examples.

These search function can search for pure and monadic predicates, of type:

> pred :: Eq b => a -> b > pred :: (Eq b, Monad m) => a -> m b

The predicates must satisfy that the domain range for any codomain value is continuous; that is, @∀x≦y≦z. pred x == pred z ⇒ pred y == pred x@ .

For example, we can address the problem of finding the boundary of an upward-closed set of integers, using a combination of exponential and binary searches.

Variants are provided for searching within bounded and unbounded intervals of both 'Integer' and bounded integral types.

The package was created by Ross Paterson, and extended by Takayuki Muranushi, to be used together with SMT solvers.

__The Module Structure__

* "Numeric.Search" provides the generic search combinator, to search for pure and monadic predicates.

* "Numeric.Search.Bounded" , "Numeric.Search.Integer" , "Numeric.Search.Range" provides the various specialized searchers, which means less number of function arguments, and easier to use.
