Problem Definition Files¶
In FitBenchmarking, problems can be defined using several file formats.
examples/benchmark_problems directory holds a collection of these
that can be used for reference.
More information on the supported formats can be found on the following pages.
Detecting problem file type¶
FitBenchmarking detects which parser to use in two ways:
For the CUTEst file format we check that the extension of the data file is sif
For native and NIST file formats we check the first line of the file
- # FitBenchmark Problem corresponds to the native format
- # NIST/ITL StRD corresponds to the NIST format
