Differences between FOIL & Sequential COvering

• seeks only rules where target literal is Ture
• performs simple hillclimbing search rather than beam search
• adding each new rule generalizes the disjunctive hypothesis so veiwed at this level the search is specific-to-general
• adding new conjuncts to each rule is a general-to-specific hill-climbing search
• 1) how to generate candidate specializations of a rule - need to accomodate variables
• 2) what performance measure to use - need to distinguish between different bindings of the rules variables
