e1005296e6
- fixed bugs in Value_by_index:
...
- avoid using bounds in standard form

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

- added some internal routines which are currently used by
...
master_mps_to_derivatives.C only
2006-02-28 19:55:14 +00:00
d7691f1dd6
- now only nonzero entries of the D matrix are output to MPS-files
2006-02-28 12:21:11 +00:00
f924ba1920
- added master_mps_to_derivatives.C
...
- added CGAL header to data_to_mps.C
- QMATRIX section is only output if D is nonzero
- added function problem_name() to MPS.h
2006-02-24 15:16:30 +00:00

- fixed bug in MPS-output where "COLUMNS" was missing in the output
2006-02-24 10:19:34 +00:00
7dd4a84585
- finished MPS-output routine (and with this also data2mps)
2006-02-23 17:36:59 +00:00
69117c5acf
- is_linear() now only returns true if D is nonzero; so far, whenever D was
...
present, is_linear() returned false
2006-02-23 15:35:05 +00:00
3364166411
- added feature to test_MPS to output the names of the variables as they occur
...
in the MPS file
2006-02-23 15:17:22 +00:00
e184d87ec1
- reverted unintended removal of assertion
2006-02-21 17:44:59 +00:00
fff7f6a07e
- fixed validity check (unboundedness)
2006-02-21 17:37:34 +00:00
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
7a42e51754
- fixed some typos in commentes
2006-02-20 15:26:07 +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

- (uups, dropped some statement in the previous commit...)
2006-02-16 15:10:36 +00:00
e3abce195b
- fixed bug: the upper-bounding mu_j(j) should do a LP-like mu_j(j) if j is a
...
slack variable
- fixed bug in which the partial pricing called mu_j(j) for a variable j which
is basic (the reason is that the active set MAY contain basic variables;
these were priced in previous revisions)

- fixed bug in which the upper-bounded version of mu_j() was never called
...
- fixed issue where the feasiblity check in update_1() was called at moments
where it need not hold
2006-02-16 13:26:41 +00:00
f98be94d6d
- prefixed atoi and exit with "std::"
2006-02-15 12:21:14 +00:00
71434b8c47
- fixed headers to new CGAL header format
2006-02-15 11:54:47 +00:00

- fixed several occurrences of cos/sin/etc. to std::cos/std::sin/etc.
2006-02-15 11:41:19 +00:00
7266163a62
- changed encodeProblem to output shifted instances of the QP's, too
...
- fixed bug in is_solution_optimal_for_auxiliary_problem() where in case of
a slack variable tau_aux was not incremented but set (= instead of +=)
- fixed bug in is_solution_optimal_for_auxiliary_problem() in which the special
artificial variable was not ignored even if it droped down to zero (and
therefore MUST be ignored)
- fixed bug in update_1() where feasibiliy does not always hold (in theory, it
does, but as documented, is_solution_feasible() need not return true); now
the assertion is only checked at certain times
- fixed several typos in comments
