Inspired by the Go Playground, let users solve small Zimpl models without the need to install anything. The models are solved on the server with SCIP. The log output and solution values are provided to the caller.

Results are also stored and can be shared between users via unique IDs from hashes of the input data.

$ ./zimplayground -h
Usage of ./zimplayground:
  -address=":8080": hostname:port of server
  -mem=100: SCIP memory limit (MB)
  -processes=4: limit on number of SCIP processes
  -scipExec="scip": (path to) scip executable
  -sleep=100: sleep before redirect to results (ms)
  -time=180: SCIP time limit (s)

It is assumed that SCIP (with Zimpl linked) is installed on the server and available in the PATH or explicitely specified as command-line flag.

See the SCIP homepage for documentation on the installation process.
