An Improved Directed Acyclic Graph Support Vector Machine

open access: yesJournal of Measurement Science and Instrumentation, 2011
In this paper,we propose an improved Directed Acyclic Graph Support Vector Machine(DAGSVM)for multi-class classification.Compared with the traditional DAGSVM,the improved version has advantages that the structure of the directed acyclic graph is not ...

Directed Acyclic Graph-Based Datapath Synthesis Using Graph Isomorphism and Gate Reconfiguration

open access: yesChips
Datapath synthesis is a crucial step in synthesis flow and aims at globally minimizing an area by identifying shareable logic structures. This paper introduces a novel Directed Acyclic Graph (DAG)-based datapath synthesis method based on graph ...

A DAG Scheduling Scheme on Heterogeneous Computing Systems Using Tuple-Based Chemical Reaction Optimization

open access: yesThe Scientific World Journal, 2014
A complex computing problem can be solved efficiently on a system with multiple computing nodes by dividing its implementation code into several parallel processing modules or tasks that can be formulated as directed acyclic graph (DAG) problems. The DAG

LCA Queries in Directed Acyclic Graphs [PDF]

open access: yes, 2005
We present two methods for finding a lowest common ancestor (LCA) for each pair of vertices of a directed acyclic graph (dag) on n vertices and m edges. The first method is surprisingly natural and solves the all-pairs LCA problem for the input dag on n vertices and m edges in time O(nm). As a corollary, we obtain an O(n2)-time algorithm for finding

The nucleolus of directed acyclic graph games [PDF]

open access: yes, 2013
In this paper we consider a natural generalization of standard tree games where the underlying structure is a directed acyclic graph. We analyze the properties of the game and illustrate its relation with other graph based cost games.
