This book is about circuit design for digital hardware or Accelerator in implementing an artificial intelligence based predicate calculus. This area of research is called Predicate Digital Design. The interesting part of research is understanding query answering on questions concerning the truth of predicate sentences. In here, predicate sentences concerning a Famous Marriage Problem is described and based on certain yes/no response, a digital design on the 1/0 binary values are used to make an integrated circuit or chip in the aim of making a specialized Accelerator or hardware in the implementation process.
