Main topic:The black box has w white mouse and B black mouse, Dragon and Princess take a mouse in turn from the box, the first to take the white mouse to win, but the dragon every time will be more run out of a mouse.Thinking Analysis:DP[I][J] means that when I have a white mouse and a J black mouse in the box, the probability of Princess winning first.Then there are 4 of transfer equations.respectively:Take it straight to the white mouse.Taking the Black mouse, Dragon also got the Black mouse,

the behavior of the Press Bar to disappear. This is not the case. The method of intermittent rewards, but instead, made these mice feel like drug addiction, and continue to press on, whether or not they can be rewarded. Jenkins then compares a fixed frequency (such as a press bar getting food four times) with a random intermittent reward, and finds that in a random reward situation, eliminating the mouse Press Bar takes the longest time. The di

Codeforces Round #105 D. Bag of mice probability dp, Http://codeforces.com/contest/148/problem/D The question is that dragon and Princess take turns pumping mice from the bag, W white teachers in the bag, and D black teachers. The Princess smokes first, and the first pulls the white mouse to win, the dragon will randomly run out of a mouse each time it is pumped. Give W and D for you to find the probability

There are 1000 barrels of wine, of which 1 barrels are poisonous. Once eaten, the toxicity can occur after 2 hours of death. Now use the mouse to do the experiment, give you 3 hours to find that bucket of poisoned wine, ask at least how many mice need. (Hint: wine can be mixed) The title, the mice after a week after a reaction, asked to find 1000 barrels a week after a bucket of wine, the minimum number of

Probability DPThe 9th question in Kuangbin summaryAh ... The data given by the topic are only the number of rats and black rat, so we can only do this (GAO) (P).Obviously can use the number of two kinds of mice as state = =My WA Approach:Make F[i][j] said from (w,b) take the mouse one until (i,j) "This time round process take" two people have been dead heat probability, it is obvious (I,J) This state win probability is I/(I+J), then the probability of

In data analysis, we often encounter the problem of missing value. The general missing value of the processing method has the deletion method and the filling method. By deleting the method, we can delete the missing data samples or variables. The missing value filling method can be divided into single variable filling method and multivariable filling method, in which the single variable filling method can be divided into random filling method, median/median filling method, return filling method

The fattest mouse in a group wins and enters the

Requirements: 1. To have linkage, the behavior of the mouse and the master is passive.2. Considering extensibility, cat calls can cause other linkage effects.Point: 1.

Probability, $DP $.$DP [i][j][0]$ says there is still $i$ a white cat, $j $ A black cat, the probability of the princess reaching the target State in case of a shot.$DP [i][j][1]$ says there is still $i$ a white cat, $j $ A black cat, the probability of reaching the target State in case of a dragon shot.At first $dp[i][0][0]$ are $1$, the answer is $dp[w][b][0]$. The recursive type is easy to write:$DP [i][j][0]=i/(I+J) +j/(i+j) *dp[i][j-1][1]$$DP [i][j][1]=j/(I+J) *i/(i+j-1) *dp[i-1][j-1][0]+j*

A mouse liked cheese, but it was put in N rooms, and there was a cat guard in these rooms. Now it is ready to trade with the cats. It has m-pound cat food and wants to use this m-pound cat food for cheese. In every room guarded by a cat, there is a cheese J [I] pound, and the cat needs f [I] pound food. If the teacher gives the cat f [I] * a % of cat food, then it can get J [I] * A % cheese. Now we know the demand for cat food and the number of cheese in each room for each cat. How can a mouse g
