Understanding the Beer Game

The Beer Game illustrates how difficult it is to manage dynamic systems. It was originally developed in the late 1950 s by Jay Forrester at MIT to introduce the concepts of dynamical systems. This blog post investigates the effect of different playing strategies.

World record debt of $199trn could drag economies into another crisis – study – American Hard Assets

See on Scoop.itGold and What Moves it.

Feb 6 (RT) — Global debt has soared by $57 trillion since the outbreak of the financial crisis in 2007, with the debt to GDP ratio jumping to 400 percent in Japan. This raises questions about financial stability and poses a threat of another crisis.
“After the 2008 financial crisis and the longest and deepest global recession since World War II, it was widely expected that the world’s economies would deleverage. It has not happened. Instead, debt continues to grow in nearly all countries, in both absolute terms and relative to GDP. This creates fresh risks in some countries and limits growth prospects in many,” according to new research carried out by consultants McKinsey in 47 countries.
The amount of world debt reached $199 trillion at the end of 2014, with the growth rate exceeding the pace of global economic expansion and the debt to GDP ratio increased from 269 to 286 percent.
“Higher levels of debt pose questions about financial stability and whether some countries face the risk of a crisis.”

The Critical Few

See on Scoop.itBounded Rationality and Beyond

To maintain stability yet retain the flexibility to adapt to changing circumstances, social systems must strike a balance between the maintenance of a shared reality and the survival of minority opinion. A computational model is presented that investigates the interplay of two basic, oppositional social processes—conformity and anticonformity—in promoting the emergence of this balance. Computer simulations employing a cellular automata platform tested hypotheses concerning the survival of minority opinion and the maintenance of system stability for different proportions of anticonformity. Results revealed that a relatively small proportion of anticonformists facilitated the survival of a minority opinion held by a larger number of conformists who would otherwise succumb to pressures for social consensus. Beyond a critical threshold, however, increased proportions of anticonformists undermined social stability. Understanding the adaptive benefits of balanced oppositional forces has implications for optimal functioning in psychological and social processes in general.

Researchers use games to evolve AI brains | Games | Geek.com

See on Scoop.itBounded Rationality and Beyond

The current complexity of the human brain is impressive enough on its own, but to imagine that humanity’s defining organ reached this peak through generations of evolution is even more mind-boggling. Neuroscientists are learning more about the brain all the time through new kinds of research, and at the University of Wisconsin-Madison’s School of Medicine and Public Health, researchers are studying how neural networks evolve by teaching computers to play video games.

The team describes how they created simple systems called “animats” and observed how the systems changed across generations in the paper “Evolution of Integrated Causal Structures Animats Exposed to Environments of Increasing Complexity.” Using a process not unlike natural evolution, the researcher team studied how the AI grew more complex in the hopes that the data could better our understanding of our brains’ complexity.
