suppy.projections

This module implements a framework for general projection methods.

Base class for all projections

Projection([relaxation, proximity_flag, ...])

Abstract base class for projections used in feasibility algorithms.

BasicProjections

BoxProjection(lb, ub[, relaxation, idx, ...])	BoxProjection class for projecting points onto a box defined by lower and upper bounds.
WeightedBoxProjection(lb, ub, weights[, ...])	WeightedBoxProjection applies a weighted projection on a box defined by lower and upper bounds.
BallProjection(center, radius[, relaxation, ...])	A class used to represent a projection onto a ball.
HalfspaceProjection(a, b[, relaxation, idx, ...])	A class used to represent a projection onto a halfspace.
BandProjection(a, lb, ub[, relaxation, idx, ...])	A class used to represent a projection onto a band.
MaxDVHProjection(d_max, max_percentage[, ...])	Class for max dose-volume histogram projections.
MinDVHProjection(d_min, min_percentage[, ...])

Underlying base class for basic projections

BasicProjection([relaxation, idx, ...])

BasicProjection is an abstract base class that extends the Projection class.

Projection methods

Methods to project onto the intersection of a constraint set.

Public projection methods

SequentialProjection(projections[, ...])	Class to represent a sequential projection.
SimultaneousProjection(projections[, ...])	Class to represent a simultaneous projection.
StringAveragedProjection(projections, strings)	Class to represent a string averaged projection.
BlockIterativeProjection(projections, weights)	Class to represent a block iterative projection.

Underlying base class for projection methods

ProjectionMethod(projections[, relaxation, ...])

A class used to represent methods for projecting a point onto multiple sets.
