Research on query optimization has traditionally focused on exhaustive enumeration of an exponential number of candidate plans. Alternatively, heuristics for query optimization are restricted in several ways, such as by either focusing on join predicates only, ignoring the availability of indexes, or in...

Efficient,\ndeclarative access mechanisms for this type of document-structured\ndocuments in general-are becoming of great importance. This paper\nreports our most recent advance in pursuit of the effective processing\nand optimization of structured document queries, which are important for\nlarge ...
The standard approach to join-query optimization is cost based, which requires developing a cost model, assigning an estimated cost to each query-processing plan, and searching in the space of all plans for a plan of minimal cost. But as the number of joins increases, the size of the ...
Polynomial Heuristics for Query Optimization
There have been several studies addressing the efficiency of different algorithms in solving TSPs. However, the number of nodes involved in these studies is far less than the modern PCB design requirement. This study is to evaluate the efficiency of documented combinatorial optimization algorithms for...
