چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...

A New Constrained Texture Mapping Method

The validity of texture mapping is an important issue for point or mesh based surfaces. This paper provides a new constrained texture mapping method which is capable of ensuring the validity of texture mapping. The method employs the “divided-and-ruled” strategy to construct a direct correspondence between the respective patches of the texture image and 3D mesh model with feature matching. The ...

Scalable Constrained Clustering: A Generalized Spectral Method

We present a principled spectral approach to the wellstudied constrained clustering problem. It reduces clustering to a generalized eigenvalue problem on Laplacians. The method works in nearly-linear time and provides concrete guarantees for the quality of the clusters, at least for the case of 2-way partitioning. In practice this translates to a very fast implementation that consistently outpe...

A Constrained Optimization Method for Community Detection

Abstract Community detection is one of the most important problems in complex network research. In recent years, great efforts have been devoted to this problem in term of evaluating the resulting community structure. Our previous work has shown that in addition to the resolution limit of Q, both Q and D suffer from a more serious limitation, termed as extra weak community phenomenon, i.e. some...
