In this paper we show that a number of NP-complete problems remain NP-complete even when their domains are substantially restricted. First we show the completeness of Simple Max Cut (Max Cut with edge weights restricted to value 1), and, as a corollary, the completeness of the Optimal ...

CHAPTER 1 12 INTRODUCTION 1.1 Importance of the Problem Although the concept of large-scale systems is quite recent in origin, its great relevance to the problems in our technologically based society is becoming more widely appreciated. The majority of societal problems are often characterized by ...
(branch, rock, etc) to keep alive, should be the primitive labor for which human starts to differ from apes.” Namely, due to the birth of hand, hominid can use many tools to solve lots of problems in practice, while animals cannot produce many tools, “animals can also use and even ...
The wave is shown in a simplified form, with no intricate details or realistic textures. The background of the image is black, which contrasts with the white and blue of the wave, making it stand out. There are no other objects or elements in the image. The style of the image is ...
In the light of the above results, the main contribution of this work is the enlargement of the tractability frontier for the minimal model finding and checking and the model minimization problems.

I assume that nodes with degree 2 don't exist or are continuously simplified because this algorithm needs to know the length of a true edge, i.e. fork-fork or leaf-fork length. If you had strings of nodes connected by unit length edges, that'd make the entire thing needlessly complicate...

In simplified words, the “data from models” turned into, or was complemented by, a “models from data”. Despite that shift of focus, the basic underlying principle did not change: state-of-the-art computer systems and state-of-the-art computational methods are combined and used to ...
Moreover, the corresponding problems of QCQP and LCoP defined in (1) and (8), respectively, have the same optimal value. If there exists (x¯,y¯)∈Rn1×Rn2 such that ‖x¯‖<a1+a2Tx¯+a3Ty¯ and a1+a2Tx¯+a3Ty¯>a4, then DF can be simplified as DF={M∈S1+n1...
