hitandrun 0.5-1

Released 2015-04-18

• Check for failures in findInteriorPoint and give clear errors.

hitandrun 0.5

Released 2015-01-06

• Add "Shake and Bake" method to sample from the boundary of polytopes.

• Modify DESCRIPTION to conform to CRAN guidelines.

hitandrun 0.4-2

Released 2014-08-04

• Add parameter to skip the elimination of redundant constraints by hitandrun() and har.init().

• hitandrun() and har.init() now correctly transform x0 if it is given.

• Bugfix: createTransform(inverse=TRUE) failed if the dimensionality was reduced by more than one.

• Expose eliminateRedundant in the NAMESPACE

• Bugfix (upper|lower)BoundConstraint

• Do not call rcdd::redundant with fewer than two constraints

• Convert all C code to '.Call interface'

hitandrun 0.4-1

Released 2014-01-14

• Detect and handle degenerate sampling spaces

• Use rational arithmetic in rcdd:: computations

hitandrun 0.4

Released 2013-11-27

• Add randomized slack LP for randomized starting point generation

• Remove "extremes" method for starting point generation

hitandrun 0.3

Released 2013-10-31

• Add solution.basis, createTransform, and transformConstraints to deal with equality constraints

• Add simplexConstraints to explicitly generate the constraints that define the n-simplex

• Add hitandrun, har.init, and har.run to provide a generalized interface to har that handles equality and inequality constraints

• Export findInteriorPoint to find an interior point of the polytope

• Add hypersphere.sample for sampling uniformly from the unit hypersphere

• Prefix C symbols with hitandrun_ to prevent name clashes

• Update package documentation extensively

hitandrun 0.2-2

• Prevent dimension reduction of arrays using drop=FALSE on indexing operations

hitandrun 0.2-1

Released 2013-07-11

• Bugfix: "extremes" seed point generation sometimes generated points outside the polytope (fixed #1)

• Documentation updates

hitandrun 0.2

Released 2012-01-10

• Initial CRAN release
