The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
Fix isnan() checks to declare main() returning 'int' and use floating
argument to isnan() avoiding recent (gcc 5) compiler noise.
Since last update:
../../.. version 5.5.2.1
- fixed a small error in new and improved MIP_stepOF function to find integer solutions.
../../.. version 5.5.2.2
- For integer models with semi-cont variables it happened sometimes that a message
"fillbranches_BB: Inconsistent equal-valued bounds for ..." occured and that the semi-cont condition
was not respected.
- New functions added: get_accuracy to get the numeric accuracy after solve.
- New functions added: set_break_numeric_accuracy, get_break_numeric_accuracy to let lp_solve return ACCURACYERROR
instead of FEASIBLE when numerical accuracy if worse then the provided values.
In the past, lp_solve only returned a non-optimal status in case of very severe numerical instability.
Now it will return already ACCURACYERROR when it finds a relative inaccuracy of 5e-7
- When reading a model from the lp-format and important issues are detected such as already bounds on variables being overruled
later with for example a bin keyword, this is now reported in the default verbose level such that this is seen easier.
08/05/16 version 5.5.2.3
- For some models with integer variables, lp_solve did not find the most optimal solution.
* No need automake to build.
* clean up subst patterns, not to break shell script.
* more 32bit and 64bit patterns
* pass down prefered environments to build.
* DL_LIBS came from dlopen.buildlinnk3.mk, need to buildlink.
lp_solve is a Mixed Integer Linear Programming (MILP) solver.
It is a free linear (integer) programming solver based on the
revised simplex method and the Branch-and-bound method for the
integers. lp_solve solves pure linear, (mixed) integer/binary,
semi-continuous and special ordered sets (SOS) models.
