The REDUCE HTN: REINFORCE

Do Schools Reinforce or Reduce Learning Gaps between Advantaged and Disadvantaged Students ?

Intra-household Resource Allocation: Do Parents Reduce or Reinforce Child Cognitive Ability Gaps?

Intra-household Resource Allocation: Do Parents Reduce or Reinforce Child Cognitive Ability Gaps? Do parents invest more or less in their high ability children? We provide new evidence on this question by comparing observed ability differences and observed investment differences between siblings in the NLSY. To overcome endogeneity issues we use sibling differences in handedness as an instrumen...

A Semantics for HTN Methods

Despite the extensive development of first-principles planning in recent years, planning applications are still primarily developed using knowledge-based planners which can exploit domain-specific heuristics and weaker domain models. Hierarchical Task Network (HTN) planners capture domainspecific heuristics for more efficient search, accommodate incomplete causal models, and can be used to enfo...

HTN Planning: Complexity and Expressivity

Most practical work on AI planning systems during the last fifteen years has been based on hierarchical task network (HTN) d ecomposition, but until now, there has been very little analytical work on the properties of HTN planners. This paper describes how the complexity of HTN planning varies with various conditions on the task networks. networks are required to be totally ordered, and (3) whe...

Utility-Based HTN Planning

We propose the use of HTN planning for risk-sensitive planning domains. We suggest utility functions that reflect the risk attitude of compound tasks, and adapt a best-first search algorithm to take such utilities into account.
