Inconsistent heuristics in theory and practice

In the field of heuristic search it is usually assumed that admissible heuristics are consistent, implying that consistency is a desirable attribute. The term “inconsistent heuristic” has, at times, been portrayed negatively, as something to be avoided. Part of this is historical: early research discovered that inconsistency can lead to poor performance for A* (nodes might be re-expanded many t...

Inconsistent Heuristics

In the field of heuristic search it is well-known that improving the quality of an admissible heuristic can significantly decrease the search effort required to find an optimal solution. Existing literature often assumes that admissible heuristics are consistent, implying that consistency is a desirable attribute. To the contrary, this paper shows that an inconsistent heuristic can be preferabl...

A* Search with Inconsistent Heuristics

Early research in heuristic search discovered that using inconsistent heuristics with A* could result in an exponential increase in the number of node expansions. As a result, the use of inconsistent heuristics has largely disappeared from practice. Recently, inconsistent heuristics have been shown to be effective in IDA*, especially when applying the bidirectional pathmax (BPMX) enhancement. T...

Using Inconsistent Heuristics on A∗ Search

Early research in heuristic search discovered that using inconsistent heuristics in an A∗ search could result in an exponential blow-up in the number of nodes expanded. As a result, the use of inconsistent heuristics has largely disappeared from practice. However, recent research has shown that they can yield dramatic performance improvements to an IDA∗ search using the BPMX enhancement. This p...

Schwab's Practical Theory: Integrate of Theory and Practice

The emergence of re-conceptualism in the field of curriculum studies caused a large rotation of identity in this field. The book titled "understanding of curriculum" by William Pinar may be considered the most outstanding work in the field. In this book, movement which affected pre re-conceptualist, are introduced as the traditional type and it is believed the new curriculum discourses should b...
