Evaluating Regular Path Queries (RPQs) have been of interest since they were used as a powerful way to explore paths and patterns in graph databases. Traditional automata-based approaches are restricted the size and/or highly complex queries, which causes high evaluation cost (e.g., memory space response time) on large graphs. Recently, although using approach based threshold rare label for gra...

OBJECTIVE To develop a new method for estimating the cost to governments of enacting public health legislation. METHODS We adopted a central government perspective in estimating costs. The parliamentary cost of legislative acts and regulations in New Zealand was calculated from the proportion of parliamentary time devoted to law-making (i.e. sitting days in the debating chamber), and the cost...

One of the advantages of estimating a conduct parameter game, compared with the Lerner index, is that the knowledge of cost shifters is suffi cient to get the “implied marginal cost”estimates. Stochastic frontier literature suffers from the same problem that it requires a detailed data set in order to estimate cost effi ciencies of the firms. This paper develops a model to estimate firm specifi...

in this paper, the concept of conjectural variation (cv) is used to specify optimal generation decision for generation companies (gencos). the conjecture of genco is defined as its belief or expectation about the reaction of rivals to change of its output. using cv method, each genco has to learn and estimate strategic behaviors of other competitors from available historical market operation da...
