In this paper, we present details of the participation of PKUTM in the Guided Summarization and AESOP tracks at TAC 2011. For the Guided Summarization task, we develop two extractive summarization systems based on manifold ranking and Integer Linear Programming (ILP) respectively. In our first system, we score the sentences by linearly combining manifold ranking scores and scores based on other...

Performance profile trees have recently been proposed as a theoretical basis for fully normative deliberation control. In this paper we conduct the first experimental study of their feasibility and accuracy in making stopping decisions for anytime algorithms on optimization problems. Using data and algorithms from two different real-world domains, we compare performance profile trees to other w...

How to efficiently mimic the wing shape and kinematics pattern of an able hovering living flier is always a concern of researchers from the flapping wing micro aerial vehicles community. In this work, the separate or combined optimizations of wing geometry or/and wing kinematic parameters are systematically performed to minimize the energy of hovering flight, firstly on the basis of analyticall...

Vol. 9 No. 4 1997 3 Spike is a performance tool developed by DIGITAL to optimize Alpha executables on the Windows NT operating system. This optimization system has two main components: the Spike Optimizer and the Spike Optimization Environment. The Spike Optimizer reads in an executable, optimizes the code, and writes out the optimized version. The Optimizer uses profile feedback from previous ...

voltage stability issues are growing challenges in many modern power systems. this paper proposes optimizing the size and location of static var compensator (svc) devices using a fuzzy weighted seeker optimization algorithm (fwsoa), as an effective solution to overcome such issues. although the primary purpose of svc is bus voltage regulation, it can also be useful for voltage stability enhance...

The joined-wing is a new concept of the airplane wing. The fore-wing and the aft-wing are joined together in a joined-wing. The range and loiter are longer than those of a conventional wing. The joined-wing can lead to increased aerodynamic performance and reduction of the structural weight. In this research, dynamic response optimization of a joined-wing is carried out by using equivalent stat...

The computational method of constrained constructive optimization was used to generate complex arterial model trees by optimization with respect to a target function. Changing the target function also changes the tree structure obtained. For a parameterized family of target functions a series of trees was created, showing visually striking differences in structure that can also be quantified by...

A shape optimization problem of cooling fins for computer parts and integrated circuits is modeled and solved in this paper. The main purpose is to determine the shape of a two-dimensional pin fin, which leads to the maximum amount of removed heat. To do this, the shape optimization problem is defined as maximizing the norm of the Nusselt number distribution at the boundary of the pin fin's con...

The most common approach to multiobjective examination timetabling is the weighted sum aggregation of all criteria into one cost function and application of some single-objective metaheuristic. However, the translation of user preferences into the weights of criteria is a sophisticated task, which requires experience on the part of the user, especially for problems with a high number of criteri...
