I'm using Scala^Z3 for using Z3 within Scala. Now for some experiments I'm doing, which involves solving problems which become very complex, in order to cancel the current calculation.

I have tried a soft timeout, which from the documentation sounded like the perfect option for me. I used it like this:

config.setParamValue("SOFT_TIMEOUT", "5200")

However, instead of just canceling the calculation, it crashes my whole Scala program with the error message "Error: invalid usage".

I've tried to use concurrency like Futures in order to prevent the main program to die, but then I can't use Z3 in my program anymore until I restart it, because I get the error message "Error: invalid usage" immediately.

Is there something I misunderstood about soft timeouts?

Thanks in advance!

Yours, Stefan Tiran

The names of options have been refactored in the 4.3.2 release, so the option is now called "smt.soft_timeout", see the answer to this SO question for more details on how to find out the names/description of the current options.
