Welcome to the Open Source Policy Center | OSPC
"Policymakers increasingly rely on computational models to predict the budgetary and broader economic impacts of current and proposed policies, especially those involving taxes and entitlements. Estimates from these models often determine a bill’s success or failure in the legislative process and public sphere. The Open Source Policy Center's first focus is supporting community-driven projects that analyze the budgetary and broader economic impact of taxes. These models are completely transparent and freely available to researchers across the country. OSPC also provides an easy-to-use online interface that allows students, policymakers, journalists, and informed citizens to interact with the models and learn for themselves about the effects of policies."

"The simulations on this site are meant to give students the ability to experiment on traditionally static textbook problems and examples. We believe experimenting with a flexible, dynamic system can give students deeper insights into core engineering concepts than that gained from solving for single snapshots of a system. Tweak variables; solve for unknowns; experiment; see what happens and figure out why. This site is also used to augment hands-on experiments, by tracking student training on lab equipment and comparing lab with simulated data. "

People Are Sickening: The Bug’s Eye View of Pandemic Games | PopMatters
"In pushing the logic of so many video games—with their insistent focus on death and domination—to its absurdist conclusion, then, the pandemic sim creates a marvelous kind of satire with ecological undertones. It makes us think twice about the kinds of games we play, and about the surprisingly asocial nature of the intelligence required to win even—or especially—the most innocuous of them. It turns the perspectiveless nature of modern gameplay in newly productive directions, asking us to experience the world as the so-called villains do. But in the end it’s still a primitive kind of game, one in which someone needs to win and someone needs to lose. By maintaining this simplistic division of the world into heroes and villains, the pandemic simulator remains tied to the misrepresentations of life that drive so much of gaming, and so much of the worldview that games represent and promote. It cannot think beyond winning as domination, and that domination—in a networked, ecological world—still looks like a lot like loss. Then again, if the developers of Plague, Inc. cannot come up with a convincing way of winning with the worldview we have created, perhaps that, too, is only appropriate."

Cooperation and the evolution of intelligence
"The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions provide the selection pressures necessary for the evolution of advanced cognitive abilities (the ‘social intelligence hypothesis’), and in recent years decision-making in the context of cooperative social interactions has been conjectured to be of particular importance. Here we use an artificial neural network model to show that selection for efficient decision-making in cooperative dilemmas can give rise to selection pressures for greater cognitive abilities, and that intelligent strategies can themselves select for greater intelligence, leading to a Machiavellian arms race. Our results provide mechanistic support for the social intelligence hypothesis, highlight the potential importance of cooperative behaviour in the evolution of intelligence and may help us to explain the distribution of cooperation with intelligence across taxa."

"This paper develops the concepts and methods of a process we will call ldquoalignment of computational modelsrdquo or ldquodockingrdquo for short. Alignment is needed to determine whether two models can produce the same results, which in turn is the basis for critical experiments and for tests of whether one model can subsume another. We illustrate our concepts and methods using as a target a model of cultural transmission built by Axelrod. For comparison we use the Sugarscape model developed by Epstein and Axtell."

How wise are crowds?
Fortunately, in a paper to be published in the Review of Economic Studies, researchers from MIT’s Departments of Economics and Electrical Engineering and Computer Science have demonstrated that, as networks of people grow larger, they’ll usually tend to converge on an accurate understanding of information distributed among them, even if individual members of the network can observe only their nearby neighbors. A few opinionated people with large audiences can slow that convergence, but in the long run, they’re unlikely to stop it.

CASOS: Home | CASOS
CASOS brings together computer science, dynamic network analysis and the empirical study of complex socio-technical systems. Computational and social network techniques are combined to develop a better understanding of the fundamental principles of organizing, coordinating, managing and destabilizing systems of intelligent adaptive agents (human and artificial) engaged in real tasks at the team, organizational or social level. Whether the research involves the development of metrics, theories, computer simulations, toolkits, or new data analysis techniques advances in computer science are combined with a deep understanding of the underlying cognitive, social, political, business and policy issues.

[1007.2774] Where is everybody? -- Wait a moment ... New approach to the Fermi paradox
The Fermi Paradox is the apparent contradiction between the high probability extraterrestrial civilizations' existence and the lack of contact with such civilizations. In general, solutions to Fermi's paradox come down to either estimation of Drake equation parameters i.e. our guesses about the potential number of extraterrestrial civilizations or simulation of civilizations development in the universe. We consider a new type of cellular automata, that allows to analyze Fermi paradox

Bezsudnov and Snarskii even derive an inequality that a universe must satisfy to become civilised. This, they say, is analogous to the famous Drake equation which attempts to quantify the number of other contactable civilisations in the universe right now.

[1005.4117] Random Numbers in Scientific Computing: An Introduction
Random numbers play a crucial role in science and industry. Many numerical methods require the use of random numbers, in particular the Monte Carlo method. Therefore it is of paramount importance to have efficient random number generators. The differences, advantages and disadvantages of true and pseudo random number generators are discussed with an emphasis on the intrinsic details of modern and fast pseudo random number generators.

PLoS Computational Biology: Evolutionary Establishment of Moral and Double Moral Standards through Spatial Interactions
Situations where individuals have to contribute to joint efforts or share scarce resources are ubiquitous. Yet, without proper mechanisms to ensure cooperation, the evolutionary pressure to maximize individual success tends to create a tragedy of the commons (such as over-fishing or the destruction of our environment). This contribution addresses a number of related puzzles of human behavior with an evolutionary game theoretical approach as it has been successfully used to explain the behavior of other biological species many times, from bacteria to vertebrates. Our agent-based model distinguishes individuals applying four different behavioral strategies: non-cooperative individuals (“defectors”), cooperative individuals abstaining from punishment efforts (called “cooperators” or “second-order free-riders”), cooperators who punish non-cooperative behavior (“moralists”), and defectors, who punish other defectors despite being non-cooperative themselves (“immoralists”).

Networked Learning Design - Occasional rants - Why serious games work - an over-simplified view
So a couple of years ago I produced a very simple little model. It suggests that serious games are great for learning because:
1. They provide motivation
2. They offer varying degrees of simulation
3. They tie experiences together through narration

Simulations in Physics
We are pleased to announce the publication of the third edition of our text, Introduction to Computer Simulation Methods by Harvey Gould, Jan Tobochnik, and Wolfgang Christian, Addison-Wesley (2006). The text introduces Java programming by example in the context of learning physics. It contains many novel applications, is accessible to a wide range of readers, develops good programming habits, and encourages student experimentation. Our goal is to teach students enough tools so that they can use computer simulations as a method of discovery in physics.

Clark Aldrich's Style Guide for Serious Games and Simulations: Serious Games: The Vision, The Hype
The advice I give my clients is to first, think initially more of a lab. For the first iteration of a serious game/interactive simulation, first worry about creating an experience that will really teach people who care about the material (either intrinsically or extrinsically) how to better understand it. I would go one step further and suggest that the content should be biased towards "learning to do" over "learning to know" (aka how to apply the material in the real world) but that is my own design bias.
