* Bumped revision
* Fixed author stringname error (damn this 1 based counting)
* Updating integration test to check for comments contained within the cells.
* Checking also for multiple comments in a sheet
Ipopt (Interior Point OPTimizer, pronounced eye-pea-Opt)
is a software package for large-scale nonlinear optimization.
It is designed to find (local) solutions of mathematical
optimization problems of the form
min_{x in R^n} f(x)
s.t. g_L <= g(x) <= g_U
x_L <= x <= x_U
where f(x): R^n --> R is the objective function,
and g(x): R^n --> R^m are the constraint functions.
The vectors g_L and g_U denote the lower and upper bounds on the
constraints, and the vectors x_L and x_U are the bounds on the
variables x. The functions f(x) and g(x) can be nonlinear and
nonconvex, but should be twice continuously differentiable.
Note that equality constraints can be formulated in the above
formulation by setting the corresponding components of g_L and
g_U to the same value.
Ipopt is part of the COIN-OR Initiative.
### 0.9.2 / 11.11.2013
commit e70dc0dbbc966ce312b45b0d44d0c3b1dc10aad6
Author: Malcolm Blyth <trashbat@co.ck>
Date: Mon Nov 11 15:53:58 2013 +0000
*Corrected compressed string formatting - *U (UTF-8) should have been *S (16-bit
string)
*Completed addition of notes hash to worksheet
*Bumped revision
*Updated reader and note
Note class no longer extends string for simplicity and debug of class (pp now
works a bit more easily)
Reader has had loads of changes (still WIP) to allow objects of class
Note and NoteObject to be created and combined in the postread_worksheet function
*Adding noteObject to deal with the Object (and ultimately text comment field)
created by excel's madness
SciPy 0.12.1 is a bug-fix release with no new features compared to
0.12.0. The single issue fixed by this release is a security issue in
``scipy.weave``, which was previously using temporary directories in
an insecure manner under certain circumstances.
Changes since 3.1.3:
Bug 620: Fix robustness and performance issues in JacobiSVD::solve.
Bug 613: Fix accuracy of SSE sqrt for very small numbers.
Bug 608: Fix sign computation in LDLT.
Fix write access to CwiseUnaryView expressions.
Fix compilation of transposeInPlace() for Array expressions.
Fix non const data() member in Array and Matrix wrappers.
Fix a few warnings and compilation issues with recent compiler versions.
Documentation fixes.
o The vignette hwde.Rnw has been modified to add missing text and to
conform to current Sweave markup conventions
o Code for the functions hwde() and make.contrasts() has been modified
so that R CMD check no longer reports "No visible binding for global
variable 'oset'."
=== 0.8.9 / 24.08.2013
Author: Doug Renn <renn@nestegg.com>

* Work around to handle number formats that are being mistaken time formats
Add missing BUILD_DEPENDS
Upstream changes:
1.07 Thu Jan 19 2012
- synchronised the autoseeding mechanism with that of Math::Random::MT
1.08 Mon May 28 2012
- synchronised the autoseeding mechanism with that of Math::Random::MT that
is more elegant and portable
1.09 Mon Jun 4 2012
- added the irand() function to draw random integers, as in Math::Random::MT
1.10 Mon Aug 6 2012
- made set_seed() return the seed, as does Math::Random::MT
- migrated test suite to Test::More and Test::Number::Delta
1.11
- Improvement of unit tests
Upstream changes:
6.22 Tue Sep 4 14:06:20 2012
- Enhancement to shuffle() to return an array
6.21 Mon Aug 6 17:27:37 2012
- Haiku does not support non-blocking IO
6.19 Fri Jul 27 00:48:20 2012
- Prevent use of incompatible state vectors
6.18 Thu Jan 26 14:58:57 2012
- Ignore warnings from other modules during tests
6.17 Wed Jan 11 05:55:09 2012
- Require OIO 3.85 to fix some 'used only once' warnings
Upstream changes:
0.31 2013-08-07
- Change proof certificate documentation to reflect the new text format.
- Some platforms were using __int128 when it wasn't supported. Only
x86_64 and Power64 use it now.
- Small speedup for ranged totient internals.
- Patch MPU::GMP 0.13 giving us not quite what we expected from a small
certificate. Fixed in MPU::GMP 0.14, worked around here regardless.
0.30 2013-08-06
[API Changes]
- Primality proofs now use the new "MPU Certificate" format, which is
text rather than a nested Perl data structure. This is much better
for external interaction, especially with non-Perl tools. It is
not quite as convenient for all-Perl manipulation.
[Functions Added]
- is_frobenius_underwood_pseudoprime
- is_almost_extra_strong_lucas_pseudoprime
- lucas_sequence
- pplus1_factor
[Enhancements]
- Documentation and PP is_prime changed to use extra strong Lucas test
from the strong test. This matches what the newest MPU::GMP does.
This has no effect at all for numbers < 2^64. No counter-example is
known for the standard, strong, extra strong, or almost extra strong
(increment 1 or 2) tests. The extra strong test is faster than the
strong test and produces fewer pseudoprimes. It retains the residue
class properties of the strong Lucas test (where the SPSP-2
pseudoprimes favor residue class 1 and the Lucas pseudoprimes favor
residue class -1), hence should retain the BPSW test strength.
- XS code for all 4 Lucas tests.
- Clean up is_prob_prime, also ~10% faster for n >= 885594169.
- Small mulmod speedup for non-gcc/x86_64 platforms, and for any platform
with gcc 4.4 or newer.
[Bug Fixes]
- Fixed a rare refcount / bignum / callback issue in next_prime.
