Summary: ANGEL stands for Automatic differentiation Nested Graph Elimination Library
Description:

ANGEL stands for Automatic differentiation Nested Graph Elimination
Library. It implements graph elimination techniques in order to find the
cheapest accumulation of Jacobian matrices. It provides:

* Sparse representation of c-graphs and their dual line graphs including
 many helper functions to work with them
* Vertex, edge, and face elimination

* Structured graph generator
* Heuristics for selecting next vertex, edge or face to eliminate

 * Lowest Markowitz degree first
 * Lowest relative Markowitz degree first
 * Minimal Fill-in
 * Maximal overall path length reduction
 * Maximal overall Markowitz degree reduction
 * Lowest Markowitz minimal damage
 * Scarcity-aware edge eliminations

* Stochastic methods

 * It is intended to optimize elimination sequences but written as
   universally as possible and can be applied to any problem where
   neighborhood relation and objective function are provided as functor
 * Metropolis with fixed temperature
 * Metropolis with fixed temperature
