with some changes and finishing of the package by me.
GLPK is a set of routines written in ANSI C and organized in the form
of a callable library. This package is intended for solving large-scale
linear programming (LP), mixed integer linear programming (MIP), and
other related problems.
GLPK includes the following main components:
* implementation of the primal/dual simplex method;
* implementation of the primal-dual interior point method;
* implementation of the branch-and-bound procedure (based on the dual
simplex method);
* application program interface (API);
* GLPK/L, a modeling language intended for writing LP/MIP models;
* GLPSOL, a stand-alone program intended for solving LP/MIP problems
either prepared in the MPS format or written in the GLPK/L modeling
language.
Remove `-p' from mkdir arguments, it is already part of ${MKDIR}.
While here substitute a couple of ${PREFIX} by `%D' in
`@exec ${MKDIR} ...' lines and add a couple of missing `%D' in such lines too!
* Fix (possible) segfaults caused by the "mid", "left" and "right"
right string functions and protect those functions and
the "replace" function against invalid arguments.
* Fix validation entry sensitivity.
* Fix some memory problems in the solver.
* Don't crash on xls import/export if locale is confused.
* Simple autodetection of tab delimited vs csv
* Avoid mistranslated font names.
* Actually disable wide character checking if it is not available.
* Fix grab when selecting a col/row with validation failure.
* Handle inserting col/row if the first is hidden.
* clone grouping and frozen status too.
* preset canvas scroll region in case something scrolls before we are
realized.
* Handle some XL export breakage cause by TagoH's patch.
* Fix advanced filter of value based implied enums.
* gdk_flush after all grab/ungrab events so that long running
operations that do not update the display are certain to ungrab
without delay (thanks rconover)
* Apply the accounting format rather than the numeric version for
Keelyn.
* Fix the omf file.
* Some gda plugin warnings.
* correct the help references in a few languages
* Fix some gcc-3 warnings.
Changes are lots of bug fixes and removal of the dependency on python.
Also enable gnumeric support so the graphing functions in gnumeric actually work.
adds several constants found in science and engineering:
- 'k' Boltzmanns constnat
- 'q' Electron charge
- 'e0' Free space permitivity
- 'mu0'Free space permeability
- 'c' Free space speed of light.
EULER is a program for quickly and interactively computing with real
and complex numbers and matrices, or with intervals, in the style of
MatLab, Octave,... It can draw and animate your functions in two and
three dimensions.
Euler features :
* real, complex and interval scalars and matrices,
* a programming language, with local variables, default values for
parameters, variable parameter number, passing of functions,
* two and three dimensional graphs,
* marker plots,
* density and contour plots,
* animations,
* numerical integration and differentiation,
* statistical functions and tests,
* differential equations,
* interval methods with guaranteed inclusions,
* function minimizers (Brent, Nelder-Mean),
* Simplex algorithm,
* interpolation and approximation,
* finding roots of polynomials,
* Fast Fourier transform (FFT),
* an exact scalar product using a long accumulator,
* Postscript graphics export
Algae is an interpreted language for numerical analysis. Algae
borrows ideas from languages like MATLAB, APL, and C, but it was
developed in response to a need for a free, efficient, and versatile
high-level language with large problem capability.
- The function whos() didn't work in the previous release,
for which reason there is this early bug fix release now.
- Since introduction of KShallowObjectArray in 1.32, I forgot to
increase the constant 12 to 13 in #define pair(ka,kb) ... in
objarithm.C. Result: E.g., 2/x where x is undefined did not produce
error message but silently evaluated to 0. There could be other much
more obscure errors also. Now the constant 12 is no longer
hard-coded but is defined to be int(Kundef)+1. This works as long as
Kundef remains the last in enum Tkind (object.H). There is comment
telling it... - in tela.C:FindMachineNan(), using switch()
statement can cause compile-time error due to duplicate case labels,
fixed now by rewriting switch() as nested if's (tela.C)
(This is in code segment that was put in tela only in the previous
release.)
- some changes to allow compilation with gcc-3.0 (contributed by Ch. Spiel)
* What is new in gsl-1.1.1:
** Fixes to histogram2d stat functions
** Added missing prototypes for complex LU determinant functions
** Improved error handling in multifit routines
** Added check to avoid division by zero for rank-deficient matrix in
multifit iteration
* What was new in gsl-1.1:
** The permutation module now includes a copy function
gsl_permutation_memcpy
** The implementation of gsl_sf_gamma_inc has been improved and now
avoids problems caused by internal singularities which occurred in the
series expansion for some combinations of parameters.
** IEEE comparisons of infinities and NaNs are tested during the
configure stage and the functions gsl_isnan, gsl_isinf and gsl_finite
are only compiled on platforms which support the necessary tests.
** The histogram routines now include a sum function,
gsl_histogram_sum for computing the total bin sum, and additional
statistics functions for 2d histograms.
** Internal error checking of user-defined functions has been improved
in the multiroots functions.
** Constants now include the Bohr Radius and Vacuum Permittivity.
** Range checking is now turned off when building the library, but is
still on by default when compiling user applications.
** A combinations directory has been added for generating combinations (n,k).
** The gamma function now returns exact values for integer arguments.
** Fixed bugs in gsl_sf_hyperg_1F1_int and gsl_sf_hyperg_1F1.
** Fixed internal error handling in gsl_sf_laguerre_n to allow
recovery from overflow.
** Several routines for handling divided difference polynomials have
been added to the poly/ directory.
** The interpolation routines now include polynomial interpolation,
based on divided-differences.
** Added new random number generators from Knuth's Seminumerical
Algorithms, 3rd Edition: borosh13, coveyou, fishman18, fishman20,
fishman2x, knuthran, knuthran2, lecuyer21, waterman14.
** Changed divisor in random number generator gfsr4 from 2^32-1 to
2^32 to prevent exact value of 1.0 from being returned, as specified
in the documentation.
New in Version 1.30:
Several vector operations are now available directly in ARIBAS
(vec1 + vec2, vec1 - vec2, lambda*vec, vec mod N , etc.)
(approved by hubertf)
Routines for GAMs and other generalized ridge regression problems
with multiple smoothing parameter selection by GCV or UBRE.
Includes an implementation (not a clone) of gam().
