Hexagonal Planning in Theory and Practice

Theory and Practice in Planning

This paper explores opportunities for synergy between theoretical and applied researchers in the area of automated planning. From the diiering perspectives of theorists, experimentalists, and practitioners, we examine the causes of current dissatisfaction with existing theoretical and experimental results. We survey approaches from theoretical computer science that provide alternatives to the s...

A Critical View on New Urbanism Theory in Urban Planning: From Theory to Practice

In the wake of Jacobs’s criticisms of planning, planners increasingly felt a level of angst over, or even responsibility for, the condition of the city. Schooled in preparing and implementing plans and land use regulations, they appreciated the appeal of a new movement that offered a simple, tangible, and marketable recipe for practice. New urbanism theory is one of the contemporary urban theor...

Language Planning: Theory and Practice

Planning with h + in Theory and Practice

Many heuristic estimators for classical planning are based on the so-called delete relaxation, which ignores negative effects of planning operators. Ideally, such heuristics would compute the actual goal distance in the delete relaxation, i. e., the cost of an optimal relaxed plan, denoted by h. However, current delete relaxation heuristics only provide (often inadmissible) estimates to h becau...

Challenges for Theory and Practice in Planning

Tiffs paper reports on recent progress addressing two issues, one of importvalce to theoretical and experimental research in generative planning and the second of importvalce to the practical application of probabilistic planning methods. The first issue concerns what makes planning problems hard from a computational perspective. We report on research investigating threshold phenomena in determ...
