class hopsy.Problem#

Attributes

`A`	Left-hand side operator $A$ of the polytope-defining inequality $A x \leq b$ .
`b`	Right-hand side of the polytope-defining inequality $A x \leq b$ .
`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 $A x \leq b$ as $A T y \leq b - A s$ 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 $A x \leq b$ as $A T y \leq b - A s$ where x = Ty + s.

Methods

slacks(point)

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