0.18 to 0.19: |
|---|
| 2 |
* Some changes for NLP/NSP solver ralg (especially related to handling linear constraints Ax <= b, Aeq x = beq, lb <= x <= ub) |
|---|
| 3 |
* Bugfix for ralg IPOPT linear constraints handling |
|---|
| 4 |
* ALGENCAN v 2.0.x has been connected (v 1.0 is no longer supported, v 2.0.3 or later is required) |
|---|
| 5 |
* bugfix for constrained NLSP graphic output (constrained nssolve isn't turned to latest ralg version yet) |
|---|
| 6 |
* scale parameter for lpSolve (p.scale = {False} | True | 0 | 1) |
|---|
| 7 |
* New OO class LLAVP (linear least absolute values aka linear least deviations) |
|---|
| 8 |
* Improved handling of non-linear functions with restricted dom |
|---|
| 9 |
* GLP (global) solver galileo now can handle integer problems (via p.useInteger = 1 or True) |
|---|
| 10 |
* Another one GLP solver connected: pswarm |
|---|
| 11 |
* Lots of work related to oofun concept (see OO Doc page for details) |
|---|
| 12 |
* Add converters llsp2nlp, llavp2nsp |
|---|
| 13 |
* Convenient handling of maximization problems (via p.goal = 'max' or 'maximum') |
|---|
| 14 |
* Some code clean up and bugfixes |
|---|
| 15 |
Backward incompatibility: |
|---|
| 16 |
* Changed objective function in LLSP |
|---|
| 17 |
* MATLAB-style gradtol renamed to gtol (for to provide same syntax to scipy.optimize fmin_bfgs, fmin_cg and less-to-type) |
|---|
| 18 |
|

| 19 |
0.17 to 0.18: |
|---|
| 20 |
* connection to glpk MILP solver (requires cvxopt v >= 1.0) |
|---|
| 21 |
* connection to NLP solver IPOPT (requires pyipopt installation, that is currently available for Linux only) |
|---|
| 22 |
* major changes for ralg |
|---|
| 23 |
* splitting non-linear constraints can benefit for some solvers |
|---|
| 24 |
* unified text output for NLP solvers |

| 25 |
* handling of maximization problems (via p.goal = 'max' or 'maximum') |
|---|
| 26 |
