Today I'll be writing about computer strategies for the classic game Roshambo, also known as paper scissors stone.
But ... but ... There's no strategy in Roshambo!
While it is true that playing random can reliably do dead average, in any tournament everyone will be trying to win, hence everyone ... | {"url":"http://www.advogato.org/person/Bram/diary/10.html","timestamp":"2014-04-19T22:11:43Z","content_type":null,"content_length":"8342","record_id":"<urn:uuid:9d3b9e5a-7d06-4d55-8069-6e403000caa0>","cc-path":"CC-MAIN-2014-15/segments/1397609537754.12/warc/CC-MAIN-20140416005217-00181-ip-10-147-4-33.ec2.internal.warc.... |

Sequential Diagnosis by Abstraction
S. A. Siddiqi, J. Huang
When a system behaves abnormally, sequential diagnosis takes a sequence of measurements of the system until the faults causing the abnormality are identified, and the goal is to reduce the diagnostic
cost, defined here as the number of measurements.

It's more complicated than that, since Phi(X1,X2), Phi(X1,X3), and Phi(X1,X4) are dependent. Take a look at:

well anyways back to my original question, I got some help from a friend and they said to start by making the (3/2)(x-1) into one term, and then multiply the sqrt by something that will allow you to
combine it with the expanded fraction, then go from there. And they said that the final solution will end up... | {"url":"http://www.mathisfunforum.com/post.php?tid=588&qid=6260","timestamp":"2014-04-20T16:34:21Z","content_type":null,"content_length":"21306","record_id":"<urn:uuid:332b732b-c313-4eb6-b7e3-3573d3a63017>","cc-path":"CC-MAIN-2014-15/segments/1397609538824.34/warc/CC-MAIN-20140416005218-00619-ip-10-147-4-33.ec2.interna... |

expectation-propagation and ABC
August 23, 2011

numerical examples) and more arbitrary, in the sense that in r... | {"url":"http://www.r-bloggers.com/expectation-propagation-and-abc/","timestamp":"2014-04-20T11:03:33Z","content_type":null,"content_length":"41462","record_id":"<urn:uuid:b618b9ca-eb34-4145-8966-05cda78eee42>","cc-path":"CC-MAIN-2014-15/segments/1398223201753.19/warc/CC-MAIN-20140423032001-00509-ip-10-147-4-33.ec2.inte... |

Parallel In-Place Merge

directly to Parallel Merge Sort. However, it was not an in-place implementation.
