Bernd Gärtner 5424f71850 - minor error/warning fixes 2007-05-01 15:55:12 +00:00

- renamed ...validation_flag() to ...auto_validation()
 2007-04-30 10:16:02 +00:00
Bernd Gärtner 25a03549d4 - copyright years brought up-to-date 
- (outdated) emails of everbody except me removed
 2007-04-27 00:34:44 +00:00
Bernd Gärtner d7a098033c - added another set of random tests (with double input, and using 
a different model)
- fixed memory leak in QP_solution
- refactored validity checks a little
 2007-04-26 23:56:44 +00:00
Bernd Gärtner a9be004d5a - added the interface validation methods to examples, 
and referred to them from the doc (+ typo fix)
 2007-04-25 01:33:32 +00:00
Bernd Gärtner 0bc86dea9d - moved certificate check out of the solver and into solution 
- at the same time, we don't check anymore by default, but there
  is an option to trigger a self-check
 2007-04-25 01:19:38 +00:00
Bernd Gärtner 060f6bf342 - minor refactoring; test_solver now also calls the interface 
methods (solve...) instead of the QP_solver directly
 2007-04-23 09:12:34 +00:00
Bernd Gärtner 6a79d4f45d - some more manual fixes 
- made partial pricing also work for high constraint/variable ratio (needs to
  be properly tested)
- added QSCORPIO as interesting additional example 
- switched to quotient output in iteration log to avoid nans
- removed filter_failure example (after all, this particular example
  was just an artifact of the bad to_double() routine of Gmpzf that I
  fixed earlier
 2007-04-20 12:31:57 +00:00
Bernd Gärtner 49ca59733c - user manual:

- fixed and added more examples, and referred to them from manual
 2007-04-14 15:39:55 +00:00
Bernd Gärtner 890c5d0fed - in Quadratic_program model, default bounds can now be configured, 
and there are some tests that cover this
 2007-04-13 16:12:08 +00:00

	  up and manipulate a program entrywise
	- old copying models removed

 2007-04-02 10:01:50 +00:00
Andreas Fabri c7e831b9ac Removed unused arguments 2007-03-27 07:49:33 +00:00
Bernd Gärtner 290d0e7e1f - fixed all occurrences of qp_A[i][j], qp_D[i][j] (qp_A[i], qp_D[i] are in 
general only convertible to the appropriate iterator types, and so the
  above will not work. The fix is to use (*(qp_A + i))[j]
 2007-03-23 10:57:07 +00:00
Bernd Gärtner 51b3b30f78 - copying models now have default/copy-constructors and assignment ops 
- test (and fixed) access to upper-diagonal entries in D

  may be ok if floating point numbers are used)

- fixed are_equal_qp function to only access entries of D on/below the diagonal
 2007-03-22 09:41:04 +00:00
