Metrics is an open-source Python library and a web-app developed at CRIL by the WWF Team (Hugues Wattez, Romain Wallon and Thibault Falque), designed to facilitate the conduction of experiments and their analysis.

The main objective of Metrics is to provide a complete toolchain from the execution of software programs to the analysis of their performance. In particular, the development of Metrics started with the observation that, in the SAT community, the process of experimenting solver remains mostly the same: everybody collects almost the same statistics about the solver execution. However, there are probably as many scripts as researchers in the domain for retrieving experimental data and drawing figures. There is thus clearly a need for a tool that unifies and makes easier the analysis of solver experiments.

The ambition of Metrics is thus to simplify the retrieval of experimental data from many different inputs (including the solver’s output), and provide a nice interface for drawing commonly used plots, computing statistics about the execution of the solver, and effortlessly organizing them. In the end, the main purpose of Metrics is to favor the sharing and reproducibility of experimental results and their analysis.

Towards this direction, Metrics’ web-app, a.k.a. Metrics-Studio, allows to draw common figures, such as cactus plots and scatter plots from CSV or JSON files so as to provide a quick overview of the conducted experiments. From this overview, one can then use locally the Metrics’ library for a fine-grained control of the drawn figures, for instance through the use of Jupyter notebooks.
