Swarm Intelligence: Craig Reynold's Boids

THE FLOCKING BEHAVIOR OF BIRDS, FISH, INSECTS AND EVEN HUMANS. CGA (computer graphics animation) of how flocks of birds, fish, or humans in a crowd move are very realistic. But they follow simple rules discovered by Craig Reynolds in 1986 i n a simulation of digital creatures he called Boids. In the 1992 film Batman Returns the swarms of computer- modeled bats and penguins used this algorithm. Crowds of people behave in the same way if you observe them going leaving the MRT, or shoving to get ahead  towards some object. The simple rules of 'flocking' from which emerge the the fascinating patterns of swarms are (1) keep a certain average distance between your nearest flockmates (avoid collision) (2) Move towards the average position (center) of the flock/school/crowd (3) Move in the average direction of the flock/school/crowd. The next time you are in a crowd see if you have unconsciously followed these rules. Flocking is a stable phenomenon but if just one of the flock br...

FAQ ON HIGH FREQUENCY ALGORITHMIC TRADING (HFAT) IN FINANCIAL MARKETS Q1.Why must I know more about HFAT? Because if you don't, you will be ignoring a major revolution that is going on in the financial markets and affects whole economies as well as individuals like you. HFAT is growing rapidly in market volume share all over the world. In America it now accounts for > 53% of all trades, in Europe 28%, Asia 18%. By asset class it accounts for 65 % of equity trades, 50 % of f utures, 40 % of options, 25 % of forex and 20 % of fixed income instruments. Q2.What does Algorithmic mean.? Algorithmic simply means a set of instructions/rules. In our IT age it means having a software program that executes these instructions automatically. Algorithmc does not automatically equate with high frequency. Many fundamentals-based institutional traders also use algorithms merely to automate their trades. These could be stop-loss Algos, Algos that break up big blocks of buy/sell so that they won...

LIFE IS A CLASS 4 CELLULAR AUTOMATA

To all the ardent Creationists and Theists who keep writing to me re the posts on 'God' on this Blog. Thanks, but no thanks. I respect your need for religion but there are many like me who don't need it. So leave us alone. Here is a re-post from my Facebook: LIFE IS A CLASS 4 CELLULAR AUTOMATA To the Creationists and Theists who inhabit my Facebook, I understand that Religion is ultimately a quantum leap of faith and it is suitable for some people. But I am impressed by my correspondence with a pastor in Georgia, USA-who did use Science to explore alternative views of the origin of the Universe and Life before taking that leap of faith. I applaud him for that though I disagree with his conclusion. He has read Richard Dawkin's many books, Stephen Wolfram's A New Kind of Science, dabbled with Artificial Intelligence, and played with Cellular Automata such as Conway's Game Of Life (available as an iOS app). Cellular Automata are a simulation of Life played ou...

From these photos (whose compilation or authorship is unknown) you can have an idea of the Indian psyche. Of a people in a hurry to climb up the steps of economic development, and of an ingenious people with a pragmatic bent of mind, with a as-long-as-it-gets-done credo. Function and form take into account the local business environment. Never mind that the results sometimes look comical to the rest of the world. On thing for sure is that you will never see the same kind of pictures in China, that other developing giant.
