I've always been suspicious of languages that do their own memory management as in "automatic garbage collection". It seems possible to me that stability issues with Java programs that run for a long time might come down to this. I've never been convinced that garbage collection algorithms are really deterministic and the longer such a program runs, the more likely it seems to me that problems will show up.

Now that the autorouter is free/open source I am hoping there will be a project page someplace so that researchers and developers can add in some design changes and improvements. I have noticed the program goes unstable if it runs for extended periods of time. There probably some bugs deeply buried in the code which eventually corrupts the boards and causes lockups. It is also am almost purely single threaded design which I think could be improved on multi-core CPUs. Great news! Thanks and have a nice day!

It is still Java but with the JIT compilers available in Java these days it is almost native. The big gain would be to make it multi-threaded. From my looking at it so far it appears to be single threaded. I would think that it would be natural for something like this to be multi-threaded.

I was afraid it would disappear forever and we’d all be screwed. Now it is part of the permanent internet landscape! Has there been a FreeRouting wiki or project page like SourceForge put up? Now that the source is available I would think people would like to understand it better and even help improve the software. The tool is now finally a standalone Windows/Linux application and that is even better. Is it still a Java application? Can it be compiled to a Windows/Linux native binary? I would think just native compilation would improve performance some if only a small amount. Thanks for letting us know about this and putting it on the wiki. Have a great day!
