ABSTRACT:

The aim of this research is to attempt the integration of a machine learning and a knowledge acquisition process. The aim is to complement the strengths of both disciplines: leveraging a human's strategic and heuristic knowledge, and supporting it with powerful empirical evaluation and search in the machine learner. An approach is presented with which one can develop heuristic algorithms for NP-hard combinatorial problems. Specifically, a demonstration is made of finding heuristic layout algorithms for detailed channel routing in VLSI chips. The machine learning techniques are based on evolutionary algorithms, while knowledge acquisition is done according to the ripple down rule paradigm.
