Enumerations including laconic enumerators

open access: yesTheoretical Computer Science, 2017
Abstract We show that it is possible, for every machine universal for Kolmogorov complexity, to enumerate the lexicographically least description of a length n string in O ( n ) attempts. In contrast to this positive result for strings, we find that, in any Kolmogorov numbering, no enumerator of nontrivial size can generate a list containing

Comparison of four agar media for the enumeration of the Mycobacterium abscessus complex

open access: yesInternational Journal of Mycobacteriology, 2020
Background: Traditional culture of nontuberculous mycobacteria (NTMs) has involved egg-based formulations (Lowenstein–Jensen medium) or defined media (Middlebrook formulations), which have disadvantages of composition complexity, availability, and cost ...

cvc4sy: Smart and Fast Term Enumeration for Syntax-Guided Synthesis

open access: yesInternational Conference on Computer Aided Verification, 2019
We present cvc4sy, a syntax-guided synthesis (SyGuS) solver based on three bounded term enumeration strategies. The first encodes term enumeration as an extension of the quantifier-free theory of algebraic datatypes.

Enumeration of octagonal tilings [PDF]

open access: yes, 2015
Random tilings are interesting as idealizations of atomistic models of quasicrystals and for their connection to problems in combinatorics and algorithms.

Lattice Enumeration with Discrete Pruning: Improvements, Cost Estimation and Optimal Parameters

open access: yesMathematics, 2023
Lattice enumeration is a linear-space algorithm for solving the shortest lattice vector problem (SVP). Extreme pruning is a practical technique for accelerating lattice enumeration, which has a mature theoretical analysis and practical implementation ...

Enumeration of 166 Billion Organic Small Molecules in the Chemical Universe Database GDB-17

open access: yesJournal of Chemical Information and Modeling, 2012
Drug molecules consist of a few tens of atoms connected by covalent bonds. How many such molecules are possible in total and what is their structure? This question is of pressing interest in medicinal chemistry to help solve the problems of drug potency,

Enumeration of the Monomials of a Polynomial and Related Complexity Classes [PDF]

open access: yes, 2010
We study the problem of generating monomials of a polynomial in the context of enumeration complexity. In this setting, the complexity measure is the delay between two solutions and the total time.

Optimization of Viability Treatment Essential for Accurate Droplet Digital PCR Enumeration of Probiotics

open access: yesFrontiers in Microbiology, 2020
Improvements offered by viability droplet digital PCR (v-ddPCR) include increased precision, specificity and decreased time to results making for an attractive alternative method to traditional plate count enumeration of probiotic products.

Methods for detection and enumeration of coliforms in drinking water: a review

open access: yesWater Supply, 2023
Ensuring the microbiological safety of drinking water is of paramount importance to protect public health. Coliform bacteria, including Escherichia coli, serve as key indicators of water contamination and the potential presence of harmful pathogens ...
