Inflation v2.0.2

This is a release that, importantly, implements a bigfix when generating and identifying physical monomials in scenarios with intermediate latents. The changes are

• Compatibility fixes and improvements: the uses of SciPy’s coo_matrix (to be deprecated) have been substituted by coo_array. Also, the library does not need networkx any more.

• Bug fixes in the generation of physical monomials in structures with intermediate latents.

• Memory and runtime improvements.

Inflation v2.0.1

This is a minor release that implements several improvements in compatibility, memory and runtime. The changes are

• Support for NumPy 2.

• Small bugfixes.

• Memory and runtime improvements by better handling of sparse objects.

Inflation v2.0.0

This is a major update of the package, which most notably adds support for linear programming inflation problems. Major changes are:

• Added support for linear programming relaxations of causal scenarios, via InflationLP. This allows to run inflation hierarchies bounding the sets of classical and no-signaling correlations, per J. Causal Inference 7(2), 2019 (arXiv:1609.00672)
• Added support for hybrid scenarios with sources of different nature, via the classical_sources argument to InflationProblem. Currently supported: classical-no-signaling (via InflationLP) and classical-quantum (via InflationSDP).
• Added support for possibilistic-type feasibility problems (via supports_problem in InflationLP and InflationSDP).
• Added initial support for structures with multiple layers of latent variables.
• Improved support for structures with visible-to-visible connections, using the notation of do-conditionals.
• Improved handling of certificates. This makes them easier to manipulate and evaluate.
• Revamped the description of monomials. This makes the codes faster and consume less memory.
