发帖数: 68 | 1 Agree with this one. Let the state space be {1,-1,2,-2}. Then the transition
matrix is
0.5 0.5 0.0 0.0
0.0 0.0 0.5 0.5
0.5 0.5 0.0 0.0
0.0 0.0 0.5 0.5
Let's revise the question a little bit:-)
if your previous throw was a head then you get +1 for H, 0 for T on the next
throw.
If your previous throw was a tail then you get 0 for H and -1 for T on the
next throw.
Is the score a Markov Chain? |

发帖数: 302 | 2 Let's say we want two H's.
After the first two throws, we have four different results:
1. HH, we end the game with 2
2. HT, we have start over again
3. TT, we have start over again
4. TH, we have 1/2 chance to finish the game with one more throw. We also
have another 1/2 chance to have another throw and then start over again.
suppose E is the number of expected throws, then the above argument can be
summarized as,
E = 1/4*2 + 1/2*(2+E) + 1/4*(2+1+1/2*E)
solve it. |

一声猛拉进去的感觉。说实话，手感不算好，进档没有那种叫做cut butter的又有阻力
又能很舒服地推进去的快感。
bmw和mini都是很顺滑，档位掉进去几乎没阻力的感觉，不过throw都比较长，尤其是
bmw。s2000是throw角度超小，进档既顺滑，进去瞬间卡住那一下又清晰。但我的车进
六档阻力明显比其他五档大，不知设计如此还是车老了。除此之外可谓完美。
我还坐在车里试过一些（原地空换挡）。gti类似mini但进档更清晰一点。brz很像
s2000，throw角度似乎还更小一点，感觉非常好。fiat 500也很像s2000，是个惊喜，

was gripped by violence after protesters and police clashed
"Oh my God. Oh no. That's crazy. One hundred people are trying to stone one

发帖数: 704 | 8 If the game rule does not prohibit throw-matches, the players have the right
to do so in order to maximize their competition interest.
If it does prohibit, then it has to define what is a "throw-match" in an
explicit way. Then the matter is if the behavior of the players can be
considered "match-throwing".
A rule or law should be UNAMBIGUOUS and enforceable, otherwise it cannot be
called rule or law.
