As opposed to traditional stores, there is no or only less guidance that helps the customers as they search. This thesis proposes a new approach for searching in online stores.

Considering heuristic search for satisficing and cost-optimal planning, we introduce the notion of global safeness of a heuristic, a property weaker than the standard safeness, which we claim is better for heuristic search. We describe one concrete approach for creating globally safe and optimality preserving heuristics by exploiting information in the history of the search via a new form of in...

well-known seismic design codes have offered an alternative equivalent static procedure for practical purposes instead of verifying design trials with complicated step-y-step dynamic analyses. such a pattern of base-shear distribution over the building height will enforce its special stiffness and strength distribution which is not necessarily best suited for seismic design. the present study, ...

A search engine retrieves the documents based on the query submitted to it. However, incorporation of user modelling, by the inclusion of past information (like the previous queries submitted and the titles of the documents clicked) is expected to increase the accuracy of the search results. Especially, in the case of short term history, such history information is highly related with the curre...
