New Islands of Tractability of Cost-Optimal Planning (2009)

Michael Katz, Carmel Domshlak

We study the complexity of cost-optimal classical planning over propositional state variables and unary-effect actions. We discover novel problem fragments for which such optimization is tractable,...

Structural Patterns Heuristics via Fork Decomposition (2009)

Michael Katz, Carmel Domshlak

We consider a generalization of the PDB homomorphism abstractions to what is called “structural patterns”. The basic idea is in abstracting the problem in hand into provably tractable fragments...

Structural Patterns Heuristics: Basic Idea and Concrete Instance (2008)

Optimal additive composition of abstraction-based admissible heuristics (2008)

Michael Katz, Carmel Domshlak

We describe a procedure that takes a classical planning task, a forward-search state, and a set of abstraction-based admissible heuristics, and derives an optimal additive composition of these...

Bundling and Vertical Relationships in Multichannel Television ∗ (Job Market Paper) (2008)

Ali Yurukoglu, Luis Cabral, John Asker, Gregory S. Crawford, Ignacio Esponda, Matt Grennan, ...

How Strong Are Weak Patents (2005)

Joseph Farrell, Carl Shapiro, Michael Katz, Mark Lemley, Josh Lerner, Robert Merges, ...

ABSTRACT. We analyze patent licensing by a patent holder to downstream technology users. We study how the structure and level of royalties depends on the patent’s strength, i.e., the probability it...

Market Structure, Organizational Structure, and R&D Diversity (2002)

Farrell, Joseph, Gilbert, Richard, Katz, Michael

Competition or Predation? Schumpeterian Rivalry in Network Markets (2001)

Farrell, Joseph, Katz, Michael

We explore the logic of predation and rules designed to prevent it in markets subject to network effects. Although, as many have informally argued, predatory behavior is plausibly more likely to...
