The fewest clues problem

Erik D. Demaine, Fermi Ma, Ariel Schvartzman, Erik Waingarten, Scott Aaronson
2018 Theoretical Computer Science  
When analyzing the computational complexity of well-known puzzles, most papers consider the algorithmic challenge of solving a given instance of (a generalized form of) the puzzle. We take a different approach by analyzing the computational complexity of designing a "good" puzzle. We assume a puzzle maker designs part of an instance, but before publishing it, wants to ensure that the puzzle has a unique solution. Given a puzzle, we introduce the FCP (fewest clues problem) version of the
more » ... Given an instance to a puzzle, what is the minimum number of clues we must add in order to make the instance uniquely solvable? We analyze this question for the Nikoli puzzles Sudoku, Shakashaka, and Akari. Solving these puzzles is NP-complete, and we show their FCP versions are Σ P 2 -complete. Along the way, we show that the FCP versions of Triangle Partition, Planar 1-in-3 SAT, and Latin Square are all Σ P 2 -complete. We show that even problems in P have difficult FCP versions, sometimes even Σ P 2 -complete, though "closed under cluing" problems are in the (presumably) smaller class NP; for example, FCP 2SAT is NP-complete. 1 given an instance as well as one solution to a search problem, is there another solution? Counting problems ask: given an instance, how many solutions are there? All three of these problem types are transformations of an original NP search problem. ASP versions of NP-hard problems are in NP by definition, and interestingly, there are NP-hard problems whose ASP versions are NP-hard as well. The counting version of a problem can be significantly harder than the original problem. It is well known that some problems in P (such as 2SAT) have #P-hard counting versions, and Toda's theorem states that such problems are as hard as the polynomial hierarchy [10]. Our results. This paper has three main contributions:

Subversive mobilities

Erik Cohen, Scott A. Cohen, Xiang (Robert) Li
2017 Applied Mobilities  
There has been an inherent bias in studies of 'mobility regimes' toward the perspective of the authorities. This article suggests the concept of 'subversive mobilities' to offer a novel perspective on the construct of mobilities regimes, by stressing the ways such regimes are penetrated by adversaries through diverse routes and practices, despite the regimes' various control and defense mechanisms. We investigate how 'smugglers' make use of weaknesses in existing mobility regimes to facilitate

The subversive mobilities of all three case studies reveal some common traits: a multiplicity of routes and means of travel, informal personal networks based on trust and retribution rather than formal organization, and interconnected series of assemblages of differently involved actors. We claim that the continued success of 'smugglers' to subvert the existing mobility regimes is their greater flexibility: they tend to be pro-active, initiating new routes and means of movement, and the cooperation of illicit and legitimate role-bearers, while the mobility regimes are mostly reactive, giving the former at least a temporary advantage over the latter. Our approach leads to a more inclusive and dynamic view of mobilities regimes, and enables a better understanding of why the 'smuggling' of goods and 'trafficking' in people is increasingly successful, despite the efforts of mobilities regimes to block these activities.

Mechanisms of Weight Regain following Weight Loss

2013 ISRN Obesity  
Obesity is a world-wide pandemic and its incidence is on the rise along with associated comorbidities. Currently, there are few effective therapies to combat obesity. The use of lifestyle modification therapy, namely, improvements in diet and exercise, is preferable over bariatric surgery or pharmacotherapy due to surgical risks and issues with drug efficacy and safety. Although they are initially successful in producing weight loss, such lifestyle intervention strategies are generally

Recently, various compensatory mechanisms have been elucidated by which the body may oppose new weight loss, and this compensation may result in weight regain back to the obese baseline. The present review summarizes the available evidence on these compensatory mechanisms, with a focus on weight loss-induced changes in energy expenditure, neuroendocrine pathways, nutrient metabolism, and gut physiology. These findings have added a major focus to the field of antiobesity research. In addition to investigating pathways that induce weight loss, the present work also focuses on pathways that may instead prevent weight regain. Such strategies will be necessary for improving long-term weight loss maintenance and outcomes for patients who struggle with obesity.

2014 Pharmacotherapy  
OBJECTIVE To describe the legal, professional, and consumer status of prescribers dispensing legend and over-the-counter drugs in the United States. METHODS Legal and academic databases were searched to identify those states that permit prescribers to dispense medications to patients and any limitations on such practice. In addition, prescribers and patients-consumers were surveyed to learn about the prevalence and perceptions of such practice. The use of drug samples was explicitly excluded

Midlevel practitioners (i.e., NPs and physician assistants) are authorized to dispense in 43 states. Thirty-two states do not require dispensing prescribers to compete additional registration to dispense medications, and 30 states require some level of compliance with pharmacy practice requirements. Prescriber dispensing is common, independent of patient age or insurance coverage. Prescriber dispensing appears driven by physician and patient perceptions of convenience and cost reductions. Future dispensing is likely to increase due to consumers' satisfaction with the practice. Consumer self-reported adverse drug reactions (ADRs) were equivalent between pharmacist-and physician-dispensed drugs, but urgent and emergency clinic ADR consultations were slightly lower with physician dispensing. CONCLUSIONS Prescriber dispensing is firmly entrenched in the U.S. health care system, is likely to increase, does not appear to increase ADRs, and may reduce urgent care and emergency department visits. The reduction in urgent care and emergency department visits requires further study to confirm these preliminary findings. KEY WORDS legal, public health, prescriber dispensing.

Authentication: Hot and cool

Erik Cohen, Scott A. Cohen
2012 Annals of Tourism Research  
Seeking to shift the discussion of the concept of authenticity in tourism scholarship from the dominant concern with tourist experiences to the more sociological problem of the processes of authentication of tourist attractions, we conceptualize two analytically distinct, but practically often intersecting, modes of authentication of attractions, "cool" and "hot". Through a range of examples, we demonstrate the implications of the two modes for the dynamics of the constitution of tourist

We furthermore explore the crucial question of who is authorized to authenticate tourist attractions, and thereby uncover issues of power and contestation in the politics of authentication.

Comparing Beliefs, Surveys and Random Walks [article]

Erik Aurell, Uri Gordon, Scott Kirkpatrick
2005 arXiv   pre-print
Survey propagation is a powerful technique from statistical physics that has been applied to solve the 3-SAT problem both in principle and in practice. We give, using only probability arguments, a common derivation of survey propagation, belief propagation and several interesting hybrid methods. We then present numerical experiments which use WSAT (a widely used random-walk based SAT solver) to quantify the complexity of the 3-SAT formulae as a function of their parameters, both as randomly

Some properties of WSAT which have not previously been reported make it an ideal tool for this purpose -- its mean cost is proportional to the number of variables in the formula (at a fixed ratio of clauses to variables) in the easy-SAT regime and slightly beyond, and its behavior in the hard-SAT regime appears to reflect the underlying structure of the solution space that has been predicted by replica symmetry-breaking arguments. An analysis of the tradeoffs between the various methods of search for satisfying assignments shows WSAT to be far more powerful that has been appreciated, and suggests some interesting new directions for practical algorithm development.

SARS-CoV-2 genome evolution exposes early human adaptations [article]

Erik Scott Wright, Seema S Lakdawala, Vaughn S Cooper
2020 bioRxiv   pre-print
The set of mutations observed at the outset of the SARS-CoV-2 pandemic may illuminate how the virus will adapt to humans as it continues to spread. Viruses are expected to quickly acquire beneficial mutations upon jumping to a new host species. Advantageous nucleotide substitutions can be identified by their parallel occurrence in multiple independent lineages and are likely to result in changes to protein sequences. Here we show that SARS-CoV-2 is acquiring mutations more slowly than expected
more » ... or neutral evolution, suggesting purifying selection is the dominant mode of evolution during the initial phase of the pandemic. However, several parallel mutations arose in multiple independent lineages and may provide a fitness advantage over the ancestral genome. We propose plausible reasons for several of the most frequent mutations. The absence of mutations in other genome regions suggests essential components of SARS-CoV-2 that could be the target of drug development. Overall this study provides genomic insights into how SARS-CoV-2 has adapted and will continue to adapt to humans.
