Unproductive code is basically useless, and may even be unsafe, and detecting parts of code that are unproductive is important to improve software quality.} #################### # TEXT OF THE NEWS # #################### ***/ [[https://www.irif.fr/~pvial/|Pierre Vial]] (IRIF) will present at LiCS 2018 an excerpt of his [[https://www.irif.fr/~pvial/defense.htm|PhD work]] at IRIF proving that every lambda-term has an infinite linear representation in the infinitary relational model. This work pioneers a technique that allows giving a semantic even to unproductive programs.
