The Minority Game is a model of interacting agents, who try to choose between two options every day, and those who are in the minority are winners. In an earlier paper, efficient stochastic strategies for this game was analyzed when the number of agents is 3, 5, 7. When the number of agents is large, the behaviour is qualitatively different, and as the discount parameter is varied, there is a s...

BACKGROUND The short stay unit (SSU) is a ward providing targeted care for patients requiring brief hospitalization and dischargeable as soon as clinical conditions are resolved. Therefore, SSU is an alternative to the ordinary ward (OW) for the treatment of selected patients. The SSU model has been tested in only a few hospitals, and the literature lacks systematic evaluation of the impact of ...

Did Southern whites leave the Democratic Party over Civil Rights or because economic development and other secular changes in the region made the party’s platform increasingly unattractive to them? Answering this central question in American political economy has been hampered by lack of micro-data on racial attitudes from both before and after the Civil Rights era. Our contribution is to uncov...

background: to determine factors that predicts icu and ward stay during hospitalization for coronary artery surgery. methods: data were collected retrospectively from 200 patients. icu and ward stay time was divided into two groups and compared by x 2 and t test and variables with a p value of less than 0.1 were included in logistic regression model. specificity and sensitivity of tests were ex...

Models of bounded rationality often lead to sharper predictions about real world outcomes than their full rationality counterparts. Full rationality in repeated interactions allows a plethora of equilibrium outcomes. In this paper, I examine the effect of bounded rationality in infinitely repeated games. In particular, does the introduction of boundedly rational agents lead to a smaller set of ...

The pursuit of greater efficiency in modern day surgery has led to the adoption and development of many new and extended nursing roles. Such roles often focus on physiological measurement to ensure patient safety before and during surgery. However, studies suggest that patients require considerable care in relation to the social and psychological effect of hospital admission, general anaesthesi...

The length of stay in inpatient and outpatient rehabilitation after an injury or illness has declined in recent years, exposing those with newly acquired neurologic disability to a risk of significant postrehabilitation health decline. Following a short stay in outpatient rehabilitation, individuals with neurologic disability have few, if any, options to continue their physical recovery after d...

Win Stay, Lose Shift as well as imitation strategies for iterated games rely on an aspiration level. With both learning rules a move is repeated unless the pay-o fell short of the aspiration level. I investigate social adaptation mechanisms for the aspiration level and their impact on the eÆciency of learning in a large population of agents that repeatedly play one round of a symmetric 2 2 game...

A class of binary decision-making tasks called the two-alternative forced-choice task has been used extensively in psychology and behavioral economics experiments to investigate human decision making. The human subject makes a choice between two options at regular time intervals and receives a reward after each choice; for a variety of reward structures, these experiments showconvergence of the...

Lewis-Skyrms signaling games (Lewis 1969; Skyrms 2010) have been studied under a variety of low-rationality learning dynamics (Barrett 2006; Barrett and Zollman 2009; Huttegger, Skyrms, Smead, and Zollman 2010; Huttegger, Skyrms, Tarrès, and Wagner 2014; Huttegger, Skyrms, and Zollman 2014). Reinforcement dynamics are stable but slow and prone to evolving suboptimal signaling conventions. A low...
