Replica Placement on Directed Acyclic Graphs

We present a constant factor approximation algorithm for the special case of DAGs having bounded degree and bounded tree-width (BDBT-DAGs).. We also present a constant

Acyclic partitioning of large directed acyclic graphs

Similar to other multilevel schemes, our tool has three phases; the coarsening phase, which reduces the number of vertices by clustering them; the initial partitioning phase,

Copula directed acyclic graphs

We introduce flexibility in the distribution by using bivariate copula densities to model connections between pairs of nodes in the network and present a new score criterion for

Acyclic Partitioning of Large Directed Acyclic Graphs

If it fails to find a solution with k parts (which means that for these given upper bound and lower bound, and this topological order of the vertices, the best partition does not have

Properties of Monotonic Effects on Directed Acyclic Graphs

Monotonic effects are furthermore used to relate signed edges on a causal directed acyclic graph to qualitative effect modification.. The theory is applied to an example concerning

Community detection in directed acyclic graphs

In other words, if we neglect the order imposed on nodes (and the direction of links) in a given DAG and maximize the conventional modularity measure, the obtained partition is close

A note on extremal results on directed acyclic graphs

Proposition 3.10. The converse is not true. The graph in the right from Figure 1 is strongly reduced. By Proposition 3.10 if ~ G is extremely reduced, then it is strongly reduced..

Reducing bias through directed acyclic graphs

Although researchers should generally not adjust for a covariate (or a marker for a covariate) that lies along a causal pathway when assessing the total causal effect, this may not

DAGGER: A Toolkit for Automata on Directed Acyclic Graphs

The work is based on a model introduced by (Kamimura and Slutzki, 1981; Kamimura and Slutzki, 1982), with a few changes to make the automata more ap- plicable to natural
