I forgot to remove debug logs from stdout in tgvoiprate, the estimated value is the last printed. Going to provide either patch or fixed version or probably cammand line right when I get home. Thx for understanding.

a quick workaround
./tgvoiprate <ref-file> <test-file> | tail -1 | cut -d' ' -f2
soon the patch and fixed build will be attached

the patch

To build the application you should have docker installed on your Linux; If your user is not in 'docker' group, 'make' should be run via sudo.

The executables are fully standalone and conform to the requirements (except for the tgvoiprate issue mentioned in previous comments).

The submitted tgvoiprate app got a score of 1781 which means it is less precise than the solution that always returned 3.0 as the result. Unfortunately, this is not good enough to compete for the prize.
