I fully agree.
No autorouter can guess which cost factors are more important than others, and 
human aid will often be necessary.

Some years ago I did a pcb with the autorouter of Eagle, and after finetuning 
all parameters I got an usable result.

A nice GUI for tuning parameters will be necessary. But a nice algorithm is 
needed too. I prefer a basically simple one (Lee's and ants is simple).

Does someone know which algorithm pcb autorouter is currently using?
