Software Research Center

The Software Research Center (CPSoftware) is a group formed by professors and students of the Federal Institute of Alagoas (IFAL). CPSoftware was founded in January 2017 for the purpose of researching and developing software solutions. The group focuses on research in the areas of programming languages, techniques and tools to support development software, quality assurance and security, and big data.
