Title:
Please merge lp-solve 5.5.2.11-2 (main) from Debian unstable (main)
Status in lp-solve package in Ubuntu:
In Progress
Bug description:
08/06/17 version 5.5.2.6 (temp release)
- Modified generating MPS file with some new options:
- MPSLINDO: Write semi-continious variables in different order as required
by LINDO
- MPSFREEFULLPRECISION: Write numbers with more precision in free MPS format
xli_MPS is modified to handle these new options.
- Reading an lp file with a semi-cont variable failed if the minimum is
larger than the maximum.
This is allowed because if the semi-cont attribute on the variables in
which case a 0 is also a valid solution.
- Some models with degeneraracy returned a "Unacceptable accuracy found"
error.
30/07/17 version 5.5.2.7 (temp release)
- Lower/Upper objective sensitivity was sometimes not given for some
variables. Was ok when scaling was disabled.
xx/xx/xx version 5.5.2.8
- Modified PHP driver for PHP 5.4
- In some cases an accuracy error was given by check_solution which was not
always true
13/03/20 version 5.5.2.9
- When a model is infeasible it can happen that the returned solution is not
initialised and returning NAN values
15/11/20 version 5.5.2.10
- write_MPS doesn't generate an SC BOUND on a variable that is
semi-continious and the upper bound is equal to the lower bound.
- The VB.NET demo application wasn't adapted yet for 64-bit
29/12/20 version 5.5.2.11
- version 5.5.2.9 introduced a problem for some models. They give infeasible
or let even lpsolve crash.
