A Sequential View of AND-Parallelism Through Partial AND-Processes
Most implementations of AND-parallelism tackle the shared variable problem by running literals in parallel only if they have no variables in common and thus are independent from e...

A Study of Empirical Learning for an Involved Problem
In real-world domains a concept to be learned may be unwieldy and the environment may be less than ideal. One combination of difficulties occurs if the concept is probabilistic an...
