Chess: sophisticated, intelligent, strategic. Or is it? Mathematical brute force can win any game, but how much would you need? And would it ruin the game, or improve it?

This is the story of computer chess...
#TuesdayThoughts #Tech
#Chess is a zero-sum game: if a move is advantageous to one player it is disadvantageous to the other. It's also a perfect information game: all positions for each player are equally visible. So it wasn't long before people tried to get a computer to master it.
In #mathematics terms chess is combinatorial: each move generates a large set of branching possibilities for further moves, bounded by poor moves on the “bottom” and good moves on the “top". This approach provides the foundation for computer chess programmes.

Today is the 124-th #birthday of #German #mathematician Heinz Hopf(1894-1971). By ISBN 3-05-500402-7,page 173, Hopf in 1925 became one of only ten men during the 124 years from 1810-1933 whom the #mathematics faculty of #Berlin gave the grade of 'summa cum laude'..
.. for his doctorate. Hopf's relatively old graduation age of 28.5 years (which is old in mathematics, esp. in Hopf's time) is clearly due to #WorldWarOne: at age 18, Hopf volunteered to serve in the #German army, which he did(as a low-ranking officer) for a full four years..
.., in particular participating in the Battle of #Verdun of 1916,in which he was wounded. While on furlough in 1917, Hopf attended mathematics lectures, in particular by Erhard Schmidt, in his hometown of #Breslau (then still a #German town), which impressed him greatly. During..

Brand-new and remarkable: #today, in a speech before #industry-representatives, chancellor Angela #Merkel used an old-fashioned, and,I think, INAPPROPRIATE,mathematical term to describe the #Brexit discussions..
.. in the #UK.

On 20180925, 9:50 CET, (cf. bdi.eu/der-bdi/termin…), chancellor Merkel said the following: "Wesentlich hängt es natürlich auch davon ab, was Großbritannien denn wirklich möchte. Auch da ist ja die Diskussion nicht so ganz eineindeutig [sic],
und, das muss ich..
.. allerdings sagen: Man kann nicht zum Binnenmarkt gehören, wenn man in EINEM Teil nur zum Binnenmarkt gehören will, aber in drei ANDEREN Teilen nicht zum Binnenmarkt gehört, und da müssen wir verschiedene, äh, vernünftige Wege [ rest drowned out by applause ]."

Expectancy = Success Rate x Reward Risk Ratio

Lets Talk About Expectancy Of Short Term Directional Trading System.

Read On (1/n)
Success Rate = No Of Profitable Tades/ No Of Loss Making Trades

Reward Risk Ratio = Average Profit Per Trade / Average Loss Per Trade

If Success Rate is 0.5 and Reward Risk 2, Then

Expectancy = 2 x 0.5 =1

For Making Profit, Expectancy Should Be Positive Number (2/n)
To Calculate Expectancy, You Need Defined System With Rules To Get Success Rate and Reward Risk. If You Have No System To Take Decisions, You Are Hanging In Thin Air and Will Never No Whether You Will Keep Making Or Loosing Money In Future (3/n)
