iDMC - version 2.0.5 released

iDMC, version 2.0.5 has been released.

The most evident change, is the new cross-platform java installer:


This works under Windows and Linux-i386.
Some other changes w.r.t. version 2.0.4:

• internal code cleaning
• removed broken ODE solver option from trajectory plot
• fixed 'Save Data as...' menu item enabling/disabling, improved related error messages
• upgraded idmclib to version 0.7.0
• idmclib version number retrieved at runtime

Report bugs to project mailing list: idmc-discussion _at_ googlegroups.com.

iDMC sources again online

iDMC, idmclib and RiDMC sources have been moved on repo.or.cz.
Here you can keep track of projects development, as well as make contributions.

By the way, googlecode source repository service is no more used.
Many reasons for that, the most important: now I can work offline, and publish changes from time to time.

Now you can get a full copy of the iDMC repository by:
$ git clone http://repo.or.cz/r/iDMC.git
Similar commands for idmclib and RiDMC.

idmclib and RiDMC 0.7.0

A new version of idmclib and of RiDMC have been released.
They're both named 0.7.0.

idmclib has a bug fix in the new 'slow' basin algorithm and improved and cleaned dynamic version info retrievial functions. This lets other software (i.e. idmclib and RiDMC) getting idmclib version number at runtime.

RiDMC has many improvements. Among others:

• cleaned and unified continuous and discrete trajectory functions in one generic function
• added more details in package man pages
  
• GUI dialog for selection of sample model file
  
• better interface for customizing basins of attraction plot

The online demo has been upgraded accordingly. Download and enjoy it!

Static linux binary released

I've released the Linux static binary of iDMC-2.0.4, for i386, 32bit systems.

This has no external dependencies so, if you have Sun Java 6, you can run it by typing from a shell prompt:

tar xjf iDmc-2.0.4-linux-i386-32.tar.bz2
cd iDmc-2.0.4
java -jar iDmc-2.0.4.jar


As usual, you can download it from the downloads section.

New BoA algorithm for idmclib and RiDMC

First of all, the news: idmclib-0.6.0 and RiDMC-0.6-0 released. They can be downloaded from the downloads section of the idmclib home page.

Special thanks to Marji Lines who, after trying out RiDMC-0.5-3, pointed out that there are interesting cases where the 'fast' BoA (Basins of Attraction) algorithm provided by idmclib simply doesn't work at all.

Following her suggestions, the slower (but sometimes more precise) algorithm already developed in the stand-alone version of iDMC has been added to the idmclib C library .

In brief, the main difference w.r.t. the faster algorithm is that there is a preliminary phase where all attractors are found, before actual plotting.

Now idmclib has a small set of new function dedicated to the new BoA algorithm, while the RiDMC package has been uppgraded accordingly, by adding 3 more options to the Basin R function. A nice example has been added to the Basin help page to illustrate this change. Have fun with it!

RiDMC demo online

I've just put online a short demo of the (work-in-progress) RiDMC R package.
It's based on RiDMC version 0.5-3, which can be downloaded from the downloads section of the idmclib project website.

Note for non-windows users: for compiling RiDMC, you will need lua-5.0 and gsl-1.8 (or compatible) development libraries available on your system.

Started development of RiDMC

Dear all,
I've started the development of RiDMC, an R package which will bring idmclib capabilities to R users.
A first source development snapshot can be downloaded from here.

Have fun with RiDMC!
