There is a model embedded in a web browser (Caprio 1998) that I would like to use in an MCMC algorithm. What is the best way to do this?

I could implement the model in my favorite language but I would like to know if it is possible to either write a web-scraping / mechanize script to evaluates the model and dumps the output into a file, or somehow capture the existing model implementation as a desktop executable.

The interface is fairly straightforward:enter image description here

And I envision a script that takes the parameters in the fields on the left side as inputs, and returns the results provided in the right column of fields as outputs:

 ./runmodel.sh 0.001 0.002 1 0.04 0.001 1.0 1.0 0.5 0 > model.out

Can I efficiently do this using the current implementation (in Java 1.0), or should I just start from scratch?

    $\begingroup$ Having the source code here web.archive.org/web/20020129140946/http://www.msstate.edu/…, wouldn't it be easier to write a simpler interface (say, getting rid of the GUI) in Java? $\endgroup$ – astrojuanlu Apr 18 '12 at 10:11
  • $\begingroup$ @Juanlu001 yep. That helps me for this specific case (but the question would still hold for the general case). I did not see that the code was available on my first pass. Thanks. $\endgroup$ – David LeBauer Apr 18 '12 at 22:16

Extracting data from a Java applet on the web seems complicated (see this answer on SO and this forum post), but if, for example, the data was available as ordinary web forms or, in general, in a more accesible way, there are some solutions in Python for web scraping:
