Presumably many people have more than one computer, such as a desktop + notebook, and many times we will open them at the same time. But have you found that if there are more than one computer set of keyboard and mouse on the table, it is very tiring to switch back and forth. If you can control all your computers at the same time by using just a set of mouse buttons, will you be excited about it?SynergyIt's a good tool for this! It allows you to share a set of keys on multiple computers and even

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

To run the code, you only need to execute the cat. cryed () method. 2. abstract the mouse and the hostScoring standard: Public interface observer{Void response ();

The observer mode is often seen in forums, mainly taking cats, mice, and masters as examples:My personal understanding is as follows:CodeAs follows: Namespace Test{/// /// Define a delegate/// Public Delegate void medelegate ();/// /// Define a server abstract class/// Abstract class master{Private string name;Public string name{Get {return name ;}Set {name = value ;}}/// /// Define an event/// Public event medelegate Eve;Public void notifly (){If (E

First probability expectation DP:)In fact, and the general DP is similar, as long as the status of the election is OK.Definition dp[i][j] means I have only white mouse J Black Mouse when the princess won the probability.Then: 1. Princess Choose white Mouse, direct win, probability: i/(I+J)2. The princess chose the black Mouse1) The Dragon chose the black Mouse, fled the black mouse; probability: j/(i+j) * (j-1)/(i+j-1) * (j-2)/(I+j-2)2) Dragon Choose Black Mouse, Escape white mouse; probability:

Test instructionsThere are w white ball in the bag B black Ball, now two people take a ball each time (do not put back), the first to take the victory of the white ball, when the hands take away a ball, the ball in the bag will randomly miss one, ask the probability of winning.Analysis:DP[I][J] Represents the I white ball in the bag J Black Ball, the initiator to take the probability of winning.There are four different casesThe initiator takes the white ball, the probability of winning 1.0*i/(I+

The theme: Beauty and the Beast are playing the game of painting pigeons. Pigeons in the cage covered with black cloth, white w only, Black has B, each time to take out a painting, who first painted white pigeons who will win. Beauty first draw, because the beast is too ugly, it every time the painting will scare away a pigeon, all the pigeons out of the cage are not in. Ask beauty to win probability. (Set if no one draws the white dove, count the Beast to win).Problem Analysis: This problem is

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

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. Linkage effect, run code as long as the cat.cryed () method is executed. 2. Abstract the mouse and the masterRating Standard: Public InterfaceObserver {voidResponse ();//The response of the Observer as if the mouse had seen the cat's reaction } Public InterfaceSubject {voidAimat (Observer obs);//for which observers, this

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

There are 1000 bottles of medicine, but one of them is toxic. After a week, the mouse will die! How many mice are needed to find toxic drugs in a week? Answers include 9, 10, 32, and 999.For example, if you have 8 bottles of medicine, you can get 3 rats...

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

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
