2015-07-02 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.16 * Fix to gosolnp for one parameter case thanks to David Lawrence Miller. * Fix to parallel gosolnp not passing multiple function arguments (bug reported by Alex Karagiannis). * rep argument in solnp.R had length rather than length.out (leading to cases name conflict). * Fix to pass new CRAN checks which only attach base. 2013-04-10 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.15 * Fixes to pass 3.0.0 2012-12-05 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.14 * Change to parallel functionality for gosolnp. Now makes use of the parallel package where the user has to pass an initialized cluster object (also fixes Windows paralllel functionality problems). 2012-05-22 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.13 * Fix to rtruncnorm call. 2012-05-22 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.12 * Fix to .onLoad in zzz.R 2011-07-15 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.11 * Added a penalty barrier function for use in the gosolnp random sampling and evaluation. * New function startpars directly returns a set of starting parameters ranked according to either a direct evaluation of the objective (excluding any inequality violations) else a penalty barrier function comprising the objective and constraints. 2011-07-06 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.1 * Correction to bug when terminating without solution (introduced in last update). 2011-05-19 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0-9 * Added more traps to catch errors in inverting the hessian during the inner step. Convergence codes are now (0 - solution), (1 - maximum iterations without tolerance), (2 - no convergence, failure to invert Hessian). 2011-01-03 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0-8 * Parallel functionality changed in 'gosolnp' function to make use of both multicore and snowfall packages (i.e. windows multicore functionality now possible). This also opens the possibility for future extensions to use snowfall with Rmpi for cluster processing. 2010-10-01 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0-7 * Some additional clarification in the documentation on the control parameters. * Corrections to gosolnp checks on the inequality violations during random parameter generation in the case of one-dimensional constraints (thanks to Matthieu Stigler). * Convergence checks in the gosolnp with multiple restarts method to avoid exiting on failure from solnp. 2010-09-22 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0-6 * Correction to gosolnp bugs introduced in 1.0-5. * Parameter vector (pars) now retains names across calls to fun, eqfun and ineqfun (previously these were removed). 2010-09-03 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0-5 * Trace parameter was not correctly passed to gosolnp. Also minor corrections to trace parameter in solnp (i.e. warnings off). 2010-06-27 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0-4 * Corrections to subnp function when single parameter passed to solver (effectively added dimension arguments to 'diag' function when updating the Hessian). 2010-03-20 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0-3 * Corrections to documentation 2010-03-10 Stefan Theussl * DESCRIPTION (Version): New version is 1.0-2 * Correction to default solver control parameters 2010-03-05 Stefan Theussl * DESCRIPTION (Version): New version is 1.0-1 * CITATION file: added 2010-03-10 Alexios Ghalanos * DESCRIPTION (Version): New version is 1.0 * Release version for CRAN * Added a function to generate random starting parameters and allow for multiple restarts of the solver. * Some more benchmark problems to test the gosolnp function. 2009-09-15 Alexios Ghalanos * DESCRIPTION (Version): New version is 0.3. * Changes to function inputs and benchmark suite and method of function evaluation. * Minor Fixes * More Checks to input functions 2009-05-21 Alexios Ghalanos * DESCRIPTION (Version): New version is 0.2. * Benchmark Problem suite created with more problems added. 2009-05-14 Alexios Ghalanos * DESCRIPTION (Version): New version is 0.1. * First upload of Rsolnp.
