Combinatorial Optimization On Massive Datasets: Streaming, Distributed, And Massively Parallel Computation
… two canonical examples of set cover and maximum coverage problems. We establish tight bounds on the space complexity of approximating set cover and maximum coverage in both single- and multi-pass streams, and build on these results to address the general problem of submodular maximization …

Determining optimal flight paths for cellular network connectivity for the transmission of real-time physiological data in support of big data analytics during airborne critical care transport
… This methodology consists of two main concepts: coverage map generation, and path planning. Coverage map generation creates a grid map of the total planning space that contains coverage information for each grid point. Coverage is calculated based on geographical and technical information …

New directions in streaming algorithms
… optimal streaming algorithms for set cover and maximum coverage, two classic problems in combinatorial optimization. Next, in the second part, we will show how to augment classic streaming algorithms of the frequency estimation and low-rank approximation problems with machine learning oracles in …

Perpetual requirements engineering
… testing techniques are limited by their coverage strength. Therefore, even when maximum coverage is guaranteed there is always the non-zero probability of having secondary effects prior to a change.

Preparing for out of hospital cardiac arrests (OHCA) in Riyadh, Saudi Arabia: A GIS scenario-modeling approach
… mosques, and schools as supply points; and the maximum coverage algorithm to model optimal locations for AED devices. Models were run for both vehicle and pedestrian travel times. Model results of current conditions indicated that 75% of household blocks were covered when vehicles were used to …

The diurnal cycle of cloud cover over southern and central Africa
… Minimum high-level cloud occurs at 1100 LST and maximum extent is reached during the evening around 1800 LST, except in locations experiencing deep convection which displayed a redevelopment of cloud in the early morning (0300 LST). This redevelopment of HLCA is hypothesised to be due to the …

The Activity of Breast Milk and Monoclonal HIV-specific Antibodies in Mother-to-Child Transmission
… PGT128 neutralization profiles resulted in 100% coverage of the variants tested. These data suggest that the epitopes targeted by these mAbs are present and accessible in both circulating and transmitted variants and that a combination of antibodies would provide maximum coverage against diverse …

Sublinear algorithms for massive data problems
… are possible for other natural problems such as maximum coverage. Finally, we study the Set Cover problem in alternate sublinear models: streaming algorithms (where one makes a small number of passes over the data using small storage), and sublinear time algorithms (where one computes the answer …

Sex Discrimination in the Insurance Market
… for men and women. They also claim that coverage and benefits for the same kinds of insurance are more limited for women than men. Finally, the claim is made that women, because of their sex, pay considerably higher premiums for health and disability insurance. Procedure. The purpose of …

Phase diagram for the co-adsorption of O and OH on Pt(100) and Pt(111) as determined by DFT
… concerns when considering adsorption at higher coverages as species have been observed to have a maximum coverage less than one monolayer (ML), such as O and OH on platinum (Pt) surfaces for use in direct methane to methanol synthesis. It has been suggested that the maximum coverages are due to …

DeepGridMCLP: A Deep Reinforcement Learning Approach to Solve the Maximal Covering Location Problem with Facilities in Continuous Regions
<p>The Maximal Covering Location Problem (MCLP) is a classic Combinatorial Optimization Problem (COP) in spatial optimization and operations research, predominatnly used for strategic public facility placement. The model’s objective is to determine the optimal locations for a fixed number of …

Wireless Communications and Networking with Unmanned Aerial Vehicles: Fundamentals, Deployment, and Optimization
… approaches significantly improve the downlink coverage for ground users, and enable ultra-reliable and energy-efficient uplink communications in Internet of Things (IoT) applications. For performance optimization, a novel framework is developed for maximizing the performance of a UAV-based …

Advancing the use of evolutionary considerations in spatial conservation planning
… for PD, e.g. getting MARXAN to solve a problem (maximum coverage) that is different to one it was designed to solve (minimum set), provided the impetus to seek a new methodology that accounts for PD while still maintaining MARXAN’s core functionality. This novel method, which maximises PD though …
