When SimCity got serious: the story of Maxis Business Simulations and SimRefinery

The game was inspired by research on real-world urban planning concepts,2,3 and although it was created as a way for players to experiment running a city, the goal was to be fun rather than accurate. “I realized early on, because of chaos theory and a lot of other things,” said designer Will Wright, “that it’s kind of hopeless to approach simulations like that, as predictive endeavors. Gro. ReLogoGettingStarted. STELLA Programming Language. Motivation Developers of intelligent applications face a problem today, since none of the currently ``healthy'' languages such as C++ or Java provide adequate environments to support symbolic programming tasks.

STELLA Programming Language

While Common-Lisp would probably still be the best language choice for many of these tasks, its dwindling vendor support and user base make it more and more difficult to justify its use. Knowledge Interchange Format. KIF has a declarative semantics.

Knowledge Interchange Format

It is meant to describe facts about the world rather than processes or procedures. Knowledge can be described as objects, functions, relations, and rules. It is a formal language, i.e., it can express arbitrary statements in first order logic and can support reasoners that can prove the consistency of a set of KIF statements. KIF also supports non-monotonic reasoning. KIF was created by Michael Genesereth, Richard Fikes and others participating in the DARPA knowledge Sharing Effort.[1] Although the original KIF group intended to submit to a formal standards body, that did not occur.

RAND CT477. 10 projections for the global population in 2050. A new Pew Research Center report examines global public opinion on the challenges posed by aging populations and analyzes projections for the populations in the U.S. and in 22 other countries.

10 projections for the global population in 2050

Here are 10 major findings regarding the demographic future of the world’s population in 2050. 1The global population is getting older: The number of people 65 and older is projected to triple by mid-century, from 531 million in 2010 to 1.5 billion in 2050. In the U.S., the population of seniors is expected to slightly more than double, from 41 to 86 million. 2The world is graying faster than the U.S.: The global median age, eight years less than in the U.S. in 2010, is projected to be only five years less by 2050. 3Who will be among the oldest?

4Trading young for old: Most countries, including the U.S., are projected to see the share of their population that is 65 and older surpass the share that is younger than 15 by mid-century. “You Have to Lead from Everywhere” Executive Summary Reprint: R1011D When responding to a complex, fast-moving crisis, leaders must constantly adapt their mental models and create a “unity of effort,” argues Allen, a retired U.S.

Coast Guard admiral and the national incident commander for the Deepwater Horizon oil spill. That’s a much bigger management challenge than approaching the job as a military operation and drawing on unity of command, and it can require nuanced and creative strategies, such as deciding to go “off book” when standard protocol simply won’t work.
