Many AI tasks can be formalized as constraint satisfaction problems (CSPs), which involve finding values for variables subject to constraints. 'vfrhile solving a CSP is an NP-coiapktte task in geneid, tractable classes of CSPs have been identified based on the structure of the underlying constraint graphs. Much effort has been spent on exploiting structural properties of the constraint graph to...

Abstract Because of the enormous economic gain it may offer, unit commitment (UC) has been a primary optimization job in daily operation planning contemporary power systems. The AC optimal flow (ACOPF) constraint is method for determining ideal load arrangement alternating current (AC) Using and ACOPF limitations to determine distribution an important approach ensure steady functioning with exa...

We define filter-tolerant powers of finite relational structures, and consider the problem of retracting such structures to their diagonal. We show that for some structures, such retractions can be readily derived from the axioms of Zermelo and Fraenkel, while at the other extreme, there are structures for which the existence of such retractions is equivalent to the ultrafilter axiom.

In this paper, we look at power optimization issues under dual supply voltage environment, with the goal of optimizing power consumption due to interconnection and gate capaci-tances. Logic level synthesis is used as a good starting point for power reduction, while subsequent placement stage mod-iies or veriies logic level design by providing more accurate estimate of power dissipation. We try ...
