MaLeS: A Framework for Automatic Tuning of Automated Theorem Provers [article]

Daniel Kühlwein, Josef Urban
2014 arXiv   pre-print
An evaluation on a subset of the TPTP library problems shows that on average a MaLeS-tuned prover solves 8.67% more problems than the prover with its default settings.  ...  This paper describes the tool and the methods used in it, and evaluates its performance on three automated theorem provers: E, LEO-II and Satallax.  ...  To use a new prover, ATP.ini and strategies.ini need to be adapted. Table 3 describes the parameters in ATP.ini.  ...

MOVING AWAY FROM TRADITION: PORTRAYAL OF MODERN WEREWOLVES AND VAMPIRES IN THE TWILIGHT SAGA

Nassima Kaid
1970 REDISCO – Revista Eletrônica de Estudos do Discurso e do Corpo  
It will evaluate body metamorphosis into vampires and werewolves discovering new dimensions of one's own identity and personality.  ...  The figure of the vampire, werewolves, and zombies keep coming back in those works although today's monsters are humanized.  ...  In doing so, Meyer has challenged some of the traditional views of werewolves as they are granted positive features and seem to stand for ideal values.  ...
