The Theoretical and Applied Computer Science Laboratory (LITA) has for research axes various theoretical and applied aspects, in particular: optimization and decision support in engineering systems, data mining and knowledge extraction, parallelism and distributed algorithms. , efficient algorithms on graphs and NP-completeness, programming semantics, total and partial computability, cellular automaton, discrete computation models.

Comprising about fifteen permanent staff, LITA is made up of two teams "Optimization, Learning and Algorithms" (OAA) and "Calculations, Graphs and Logic" (CGL). In a nutshell, the research axes of the OAA team revolve around Business Intelligence while those of the CGL team are in the field of Theoretical Computing.

LITA has to its credit a scientific production of significant quality and volume. In addition, it pursues a sustained activity of organizing conferences and publishing special newspapers. Close collaboration exists with many foreign research centers, in particular with universities in Germany, England, Canada, the United States, Finland, Luxembourg, Morocco, Norway, Portugal, Russia, Vietnam...
