The Complexity of Enumeration and Reliability Problems

SIAM journal on computing (Print), 1979
The class of $# P$-complete problems is a class of computationally eqivalent counting problems (defined by the author in a previous paper) that are at least as difficult as the $NP$-complete problems.

Ranked Enumeration of Conjunctive Query Results

International Conference on Database Theory, 2019
We investigate the enumeration of top-k answers for conjunctive queries against relational databases according to a given ranking function. The task is to design data structures and algorithms that allow for efficient enumeration after a preprocessing ...

Covariates and Mixture Modeling: Results of a Simulation Study Exploring the Impact of Misspecified Effects on Class Enumeration

, 2016
For some time, there have been differing recommendations about how and when to include covariates in the mixture model building process. Some have advocated the inclusion of covariates after enumeration, whereas others recommend including them early on ...

Enumeration Degrees and Enumerability of Familes

Journal of Logic and Computation, 2009
We study the enumerability of families relative to the enumeration degrees. It is shown that if a family of finite sets is e-reducible to every non-zero e-degree, then the family is computably enumerable (c.e). On the another hand, we will find a non-c.e. family which is e-reducible to all non-zero e-degree.

Recovery and Enumeration of Viable Bacteria

SSSA Book Series, 2018
One of the greatest challenges facing soil microbiologists for more than a century has been the recovery and enumeration of "total" bacterial populations in soils.

Enumeration of Platelets

American Journal of Clinical Pathology, 1978
A correlation of the enumeration of platelets in peripheral smears with platelet counts performed by a direct method is presented. A ratio of 1 platelet per oil-immersion field for every 21,000 platelets of the chamber count indicates the normal average range of platelets to be approximately 7--21 per oil-immersion field.

Scalable Distributed Subgraph Enumeration

Proceedings of the VLDB Endowment, 2016
Subgraph enumeration aims to find all the subgraphs of a large data graph that are isomorphic to a given pattern graph. As the subgraph isomorphism operation is computationally intensive, researchers have recently focused on solving this problem in ...

DUALSIM: Parallel Subgraph Enumeration in a Massive Graph on a Single Machine

SIGMOD Conference, 2016
Subgraph enumeration is important for many applications such as subgraph frequencies, network motif discovery, graphlet kernel computation, and studying the evolution of social networks.
