Dear COIN-OR community,

I am pleased to announce the release of CMPL 1.9.0.

New main features and change log (full description

jCMPL (v.1.0)
jCMPL is the CMPL API for Java. 

As in pyCMPL - the main idea of this API is to define sets and
parameters within 
the user application, to start and control the solving process and to
read the 
solution(s) into the application if the problem is feasible. 

All variables, objective functions and constraints are defined in CMPL. 

These functionalities can be used with a local CMPL installation or a

CMPL (v.1.9.0) 
- Direct access to a CMPLServer by the new command line argument
-cmplUrl <url> 
 Most of the command line arguments used for a local CMPL installation
can be used.

- CBC handling is now faster and less memory consuming because Cmpl
 now directly with CBC. 

- readcsv
A vector now can be read as a row with n elements or n rows with one
In booth cases a column vector is created.

- MPS file handling of constraints with type N (e.g. inactive objective
These constraints or inactive objective function are committed as
with type "G" and an lower bound equal to negative infinity.
This behaviour avoids the deletion by solver preprocessing and as result
constraints or inactive objective function can be shown in the solution

pyCMPL (v.1.2)
- Most of the CMPL command line arguments can now used with to a

- Additional methods Cpml.getVarByName(self, name, solNr=0) and 
 Cpml.getConByName(self, name, solNr=0) to obtain variables and
 directly by their name. 

CMPLServer (v.1.2)
- Version and compatibility check for CMPLServer clients 

- New options that can be defined in the new pyCmpl option file
- maxProblems - Maximum number of problems that can be solved in
parallel (default 8)
- maxInactivityTime - Inactivity time (in seconds) after that a problem
 removed from the CMPLServer (default 60*60*12)
- port - Port of the CMPLServer  (default 8008)

- new class CmplInfo to support the transfer of some CMPL statistics and
the generated matrix

Coliop (v.1.19)
- Some minor changes to enable an access to a CMPLServer.
