vegas version 5.0

New, much improved implementation of vegas.PDFIntegrator. It is slightly incompatible with the previous version but offers much more functionality and is faster. Also fixes a further bug when max_nhcube=1.

vegas version 4.0.3

Fixes bug when max_nbatch=1.

vegas version 4.0.2

Bug fix for (rare) problem that can occur when an integrand vanishes everywhere.

vegas version 4.0.1

Fixes bug for Windows machines.

vegas version 4.0

This version uses a somewhat different algorithm for setting the stratification used by the adaptive stratified sampling in vegas. The new stratification strategy will have a negligible effect for many applications, but it can make vegas significantly more stable in very high dimensions or when the number neval of integrand samples per iteration is small. See Sec. 3.2 in arXiv:2009.05112 for examples.

vegas version 3.5.4

Minor update to fix a bug when minimize_mem=True. Also reset default for max_neval_hcube to 1e5.

vegas version 3.5.3

Fixes bug introduced by last bug fix, again for Windows machines.

vegas version 3.5.2

Fixes bug on Windows machines due to mismatched integer types.

vegas version 3.5.1

Small software update; no code changes.

vegas version 3.5

Adds new functionality: vegas.AdaptiveMap.adapt_samples(x, f) can be used to precondition vegas before integrating; and different directions can have different numbers of stratifications. See new sections in the tutorial on "vegas Map and Preconditioning vegas" and "vegas Stratifications" for more information.
