Getting a grip on Complexity Quick demonstration activity

How the idea got started Resilience Robustness

Complexity & the game of Go "Chess lies on the boundary between the tasks best accomplished by careful co‐ordination and design – the strengths of planning – and those best accomplished by experiment and adaptation – the strengths of markets." ‐ John Kay, Economist

Complexity & the game of Go Chess Go • 8 x 8 board • 19 x 19 board • Play in squares • Play on lines • Kings, Queens, Bishops, • Black stones and White Rooks… stones • Aim: to kill the other • Aim: to surround more players King territory • 1st 3 moves = 4,352 • 1st 3 moves = 46,655,640

What is Go? • Go is a board game • It is played all over • It originally came from the world, but Tibet / China mainly in • Created ≈ 2300 B.C. • Japan (iGo), • China (Weiqi) & • Korea (Baduk) • Have you seen it before? Picture from www.igs.com

History of Go • Played by the nobles • Generals practiced it for war • Simple = Pure Strategy • Cultured = Calligraphy + Archery + Haiku + Go • Taught in 5 Schools

Basic Rules • Start with a small, empty board • Each player takes a turn placing one stone 4 3 anywhere on the board • Each stone has liberties 2 1 • When a stone has no more liberties it is captured and taken from the board

Basic Rules • When two stones are placed next to each other they form an army • An army has to lose ALL its liberties to be captured • The bigger an army is, the stronger it is • Whoever surrounds the most intersections wins the game

Practice Games

Some hints to get started 1. Don’t start near the edge 2. Place fence posts 7 1 then the palings 8 2 3 3. Surround as 1 3 4 5 much area as 2 6 possible 1 2 4. Try not to play up against the other player White Black will win will win

Lets Play Go!

Scoring a Go game Black: 18 + 1 = 19 The winner is determined by their score Score = Points Surrounded + Prisoners taken Rankings & Handicaps White: 15 + 5 = 20

Complexity & the 2 rules of Go From a basic framework and two simple rules comes amazing complexity 1. Suicide Rule 2. Ko Rule

Influence & Future Constraint The famous ear‐reddening game – 1846 Inseki v Shusaku

Influence & Future Constraint Why is move 127 so powerful? It strongly influences many possible future moves

Complicated v Complex Complicated Complex More constrained Less constrained Stable Unstable Similar input = similar output Small changes => unpredictable results Manage results Manage boundaries & attractors Set Objectives Set Outcomes Break down to details Chunk up & experiment Apply Best Practice Use Safe‐Fail to discover what works Dave Gray, Founder XPLANE > “When you make the complicated simple, you make it better. But when you make the complex simple, you make it wrong.”
