- fixed warnings (mainly unused variables in functions overloaded by tags)
2007-02-22 10:07:00 +00:00
5a76699d6d
- removed C-files under include/CGAL
2007-02-16 15:40:25 +00:00

- redundant friend removed; iterators now returned as "const Iterator" in the
...
hope of pleasing Menelaos' debugged g++ platform

is using it now
2006-09-28 16:50:59 +00:00

68fc833cb5
- Is-symmetric tag removed; now all input is assumed to be symmetric.
...
Reason: the tag is unecessary, and allowing non-symmetric input only
allows the user to enter redundant information
2006-09-28 14:29:33 +00:00
a52c3881b6
- tag "Has_equalities_only_and_full_rank" removed; this is now handled
...
dynamically in the code. Reason: this tag is difficult to explain to
the user, does not have any effect on the interface, and is not very
costly to dispatch dynamically

- basic interface for QP_solution enhanced; interface types and names
...
are now consistently only introduced in QP_solution, while the virtual
functions in QP_solver_base are implementation-centered
2006-09-26 09:54:39 +00:00

f9ff2cfb36
- added make_qp function (more will follow: make_lp, make_nonnegative_lp,...)
...
- moved write_MPS out of QP_from_mps and made general
- introduced QP_solution as ref-counted wrapper for QP_solver pointers
2006-09-13 21:10:11 +00:00
7464866235
- added QP models
...
- refactored QP_solver to separate the QP, the ET and the Tags
- got rid of MPS.h, MPS.C (integrated into QP_models)
- added QP_functions.h to test full rank of QP
- added QP_solver diagnostics for friends to access
- removed ET type from MPS reader (was only needed for rank test, and now
I'm using the new QP function for that -> faster and cleaner)
2006-09-09 14:58:32 +00:00

removed configurable row type, now CGAL::Comparison must be used
2006-09-05 12:32:25 +00:00
6d9fb3278d
- adapted all pricing strategies to deal with nonstandard form
...
- made pricing of a single variable a method in base class QP_pricing_strategy
- added missing pricing strategy notification in enter_and_leave_variable()
2006-09-05 11:45:44 +00:00
33cdafd438
- adapted to new type Gmpzf
...
- fixed some possible sources of ambiguity: all arithmetic ops now
have both operands of the same type
2006-08-31 11:27:31 +00:00
1d057b9e59
enhanced MPS parser. It can now handle
...
- NAMEs with spaces
- RANGES
- RHS entry for objective row (means: constant term in obj func)
enhanced QP_solver. It can now handle a constant term in obj func
2006-08-24 14:12:24 +00:00
b8b1810b58
- added some additional assertions
...
- in write_MPS, 0's are now omitted
- added routine to read floating-point number in decimal format from MPS
- fixed two bugs that didn't have any effect (yet)
- commented out some expensive checks / long outputs in example programs

fixed bug that led to wrong objective function values
2006-05-30 14:31:16 +00:00
e1005296e6
- fixed bugs in Value_by_index:
...
- avoid using bounds in standard form
- included denominator handling
- included new Variable_numerator_iterator in feasibility test
2006-03-06 14:22:18 +00:00
e520a96fa3
- removed old (not useful) variable iterators that go over the whole
...
set of working variables; instead, the same iterators now only go
over the original variables
2006-03-03 18:56:43 +00:00
27289d34c0
- added original_variables_numerator_iterator
...
and original_variables_value_iterator
- tested this new functionality as part of test_MPS.C
- adapted Trung's example to work with it and checked it in
2006-03-03 18:32:37 +00:00
2586165bee
- fixed bug in ratio test for positive mu
...
- derivative generation is suppressed upon comment in mps-file
- warnings seen in -o3 fixed
2006-03-02 15:57:23 +00:00
3364166411
- added feature to test_MPS to output the names of the variables as they occur
...
in the MPS file

662b8e87aa
- solver now provides routine mu_j(int j) to the pricing strategies which
...
computes the exact mu_j in both the standard form and nonstandard form case
- fixed bug in ratio_test_1__t_j() where mu_j was not correctly computed for
problems in nonstandard form
2006-02-21 13:27:43 +00:00
6fae29186c
- moved QP_solver.C from CGAL/ to CGAL/QP_solver/
2006-02-20 14:55:55 +00:00
1b666993c1
- fixed bug in validity check (optimality of auxiliary problem): the previous
...
revision only checked the KKT conditions for the problem in standard form
- added simple (and inefficient) class Bnd that represents a possibly infinite
bound; the class is used in the validity check
2006-02-20 14:00:28 +00:00
c731057bbd
- fixed bug in which the upper-bounded version of mu_j() was never called

where it need not hold
