wmpy.integration.cache.CacheWrapper

class CacheWrapper(integrator)

Bases: object

This class implements a cache wrapper around an Integrator.

The returned type of the integration calls is the same of the enclosed integrator.

integrator

the enclosed integrator instance

cache

a dictionary mapping _compute_key(Polytope, Polynomial) into results

Methods

integrate	Computes a convex integral.
integrate_batch	Computes a batch of integrals.

integrate(polytope, polynomial)

Computes a convex integral.

If the result is not yet available in the cache, the enclosed integrator is called (and the result is added to the cache).

Parameters:

• polytope (Polytope) – convex integration bounds (a Polytope)

• polynomial (Polynomial) – integrand (a Polynomial)

Return type:

float

Returns:

The result of the integration as a non-negative scalar value.

integrate_batch(convex_integrals)

Computes a batch of integrals.

Parameters:

convex_integrals (Collection[tuple[Polytope, Polynomial]]) – a collection of bounds/integrand pairs

Return type:

ndarray

Returns:

The result of the batch of integrations as a numpy array.
