Effectively Encoding SAT and Other Intractable Problems into Ising Models for Quantum Computing
… to solve a particular optimization problem. Problems such as SAT and MaxSAT need to be encoded to make use of quantum annealers. Encoding SAT and MaxSAT problems while respecting the constraints and limitations of current hardware is a difficult task. This thesis presents an approach to …

Investigating the Complexity of Community in a Challenged Urban Elementary School
… of students at the school, and (c) the intractable problems that exist within the school, both on micro and macro levels. Based on these findings, the main conclusion was that teachers played the biggest role in prioritizing students, as they were the community members most immersed with …

DYNAMIC DEFENSES AND THE TRANSFERABILITY OF ADVERSARIAL EXAMPLES
… which may be the solution to one of the most intractable problems in adversarial machine learning. We go on to implement a minimal experiment, demonstrating that research within this area is easily accessible. Finally, we address some of the hurdles to overcome in order to unify the disparate …

Relaxation Adaptive Memory Programming For The Resource Constrained Project Scheduling Problem
… scheduling problem (RCPSP) is one of the most intractable problems in operations research; it is NP-hard in the strong sense. Due to the hardness of the problem, exact solution methods can only tackle instances of relatively small size. For larger instances commonly found in real applications …

Generalized Volterra-Wiener and surrogate data methods for complex time series analysis
… new robust approaches to solving classically intractable problems. Part I presents a comprehensive review of various classical approaches to time series analysis from both deterministic and stochastic points of view. We focus on using these classical methods for quantification of complexity in …

New neighborhood search algorithms based on exponentially large neighborhoods
A practical approach for solving computationally intractable problems is to employ heuristic (approximation) algorithms that can find nearly optimal solutions within a reasonable amount of computational time. An improvement algorithm is an approximation algorithm which starts with a feasible …

High-order retractions for reduced-order modeling and uncertainty quantification
… quickly, our appetite to solve larger and larger problems grows just as fast. As a consequence, reduced-order modeling has become an essential technique in the computational scientist's toolbox. By reducing the dimensionality of a system, we are able to obtain approximate solutions to otherwise …

The Control of Various Bermudagrass Cultivars in Tall Fescue Utilizing Fenoxaprop & Fluazifop
… desirable turfgrass species, is one of the most intractable problems a turf specialist encounters. Herbicides previously used to selectively control bermudagrass such as siduron and oxadiazon have proven to be of only minimal efficacy or to induce significant injury to other desirable …

The international mechanisms relating to mutual assistance in the field of information exchange and civil forfeiture
… and second, to identify some of the most intractable problems encountered by justice authorities in their attempts to attach property situated abroad. The idea is to identify the principal point of discordance, and to suggest ways in which the international instruments governing civil …

Examining price appreciation in foreclosed properties
… to remediate defects in the property or to cure problems due to endemic disinvestment. On the other hand, it is quite probable there is a negative effect due to intractable problems and or stigma which cannot be cured with money or sweat equity; i.e. socio-economic factors such as changes in …

Thatcherism and the restoration of governability
… if immeasurable, credibility and legitimation problems. To what extent have the Thatcher policies solved these seemingly intractable problems? Has Thatcherism found a solution to the demands of social democratic Britain? What is the real extent of Britain's economic recovery? Is there a "new …

Zozobra: the tensions of urban space
… starts from a practical perspective: that of the intractable problems of our inner cities; inadequate service delivery, absent infrastructure, poverty, unemployment. Themes unquiet and persistent. I offer a critique of approaches to policy and argue that post-structural theoretical shifts offer …

Health systems thinking : the need for a more critical approach
… more critical approach to deal with some of the intractable problems encountered in current health sector reforms. The thesis is not expected to serve public health practitioners only but also systems thinking theorists, particularly those interested in social systems and pluralism in management …

When all information is not created equal
… novel approaches for simplifying such difficult problems in information theory. Our formulations are based on ideas from graphical models and Euclidean geometry and provide canonical examples for network information theory. They provide fresh insights into previously intractable problems as well …

Building Maze Solutions with Computational Dreaming
… solutions to, for example, NP-hard or previously intractable problems.

Particle size prediction in reactive precipitation processes
… of DPB routines into CFD codes results in intractable problems.;One excellent alternative to the DPB is the Quadrature Method of Moments (QMOM), which provides a very useful closure to the moment-transformed population balance equations. The QMOM is very attractive for CFD applications …

Who Speaks for the State? Narration, Representation, and the JCPOA
… for engaging with ‘implacable’ adversaries on ‘intractable’ problems. Although the obstacles to success were formidable, in 2015, Iran, the United States, and the other P5+1 states announced the Joint Comprehensive Plan of Action (JCPOA). Under this agreement, Tehran accepted verifiable …

Making Sense of Pain: A Pluralist Remedy for Pain Eliminativism
… and sense concepts, by first developing three intractable problems for which current theories cannot account, these being: Perceptual Objectivity, Mechanistic Disparity, and Phenomenal Heterogeneity. Stemming from the requirements these three problems methodologically impose, I develop a novel …

Educational Decentralisation in a Developing Country: A Case Study of the School Transfer Policy in the Thai Education System
… However, this study suggests that some of these intractable problems might be overcome through a culture of cooperative innovation, practice sharing, or develop professional learning communities which could help move implementation to a new phase of implementation and development. Any education …
