hopsy.Problem

class hopsy.Problem

Attributes

A	Left-hand side operator \(A\) of the polytope-defining inequality \(Ax \leq b\).
b	Right-hand side of the polytope-defining inequality \(Ax \leq b\).
model	The model object defines the target distribution inside the polytope via its log_density().
original_A	If the Problem has been transformed, e.g., rounded, then sometimes one wants to reconstruct the original problem.
original_b	When the Problem has been transformed, e.g., rounded, then sometimes one wants to reconstruct the original problem.
shift	For preconditioning (e.g. polytope rounding) one may wish to transform the polytope defined by \(Ax \leq b\) as \(ATy \leq b - As\) where x = Ty + s.
starting_point	A single starting point as part of the problem.
transformation	For preconditioning (e.g. polytope rounding) one may wish to transform the polytope defined by \(Ax \leq b\) as \(ATy \leq b - As\) where x = Ty + s.

Methods

slacks(point)

Given a point` computes polytope slacks, i.e., b - A * x.
