"SD-Grundy function" We will face more variants related to the NIM game, and we will also seeA1 ^ A2 ^... ^This value is more extensive. In the above article, we carefully studied the NIM game and learned how to find a winning strategy. But if you add or change the NIM rules, can you quickly find a winning strategy? For example, if there are n piles of stones, o

Test Instructions:LinkMethod:Game + Constructionparsing:God did not think of what to do, after reading the words of WYF uncle to understand the problem of the test instructions is n heap of stones, after you each operation there are two ways the first is the NIM game has been established on the Nim game. The second option is to select several heaps in the unchecked heap to join the

Nim gamesNim games are one of the most classic models in game theory ?), It has simple rules and the conclusion that there is no beautyNim games are a kind of combinatorial games. Specifically, they belong to impartial combinatorial games (ICG ). An ICG game meets the following conditions (which may not be rigorous): 1. Two players are involved; 2. Two players move the game alternately, players can choose one of the limited legal mobile sets to move;

Consider the point query of the tree array interval modification (which affects only the answers to its subtree), and each point records its weight-to-value XOR on the root path.Answer when query (L) ^query (R) ^a[lca].This method avoids tree chain splits when asked on a tree that supports interval addition and subtraction.May explode stack, consider manual open stack. (Eh eh Tarjan pretreatment LCA when did not manually open the stack?) Don't mind ^_^)It's not actually going to explode.#include

topic: http://acm.hdu.edu.cn/showproblem.php?pid=1907 : Nim game, but the last time the person failed, output the winner of the idea: ANTI−SG:ANTI-SG:ANTI−SG ANTI-SG Game rules, the decision set for the empty game player wins. ANTI−SG ANTI-SG Other rules are the same as SG SG Games. SJ theorem: sj theorem:For any ANTI−SG ANTI-SG game, if we stipulate that the SG SG value of all the single games in the situation is 0 0 o'clock, the game is over, then

The First gives a conclusion: if there are n piles of matches, each match has A1, A2, a3...an matches, under the rule of the traditional Nim game, if A1^a2^a3^...^an=0 will lose. And these two conclusions are completely equivalent, that is to say, if you do not meet this condition, you will win. then in the subject, after picking up some matches, if the remaining matches have a subset of the match or 0, then the next hand to remove the other matches

When asked whether traditional raid can be built on SSD, the first response should be "yes, but trim command support is required ". On the Internet, we can also see that many people use SSD to create raid, but basically it is configured as RAID 0 or raid 1. Few people will build RAID5. Why? The answer is very simple. If you configure parity-raid like RAID 5 on the basis of

From today on, I will use a series Article This section describes the basic knowledge of game theory, which is mainly used in Oi. Of course, I have a superficial understanding of game theory, and the style of my writing has always been a "Personal Experience" rather than a "evangelism" type. So if you want to study game theory carefully, I strongly recommend that Professor Thomas S. Ferguson from the University of California carefully write and provide this teaching material for free, which has

Today, I made a game question in poj. I learned about the tiered game... I will explain my understanding of the tiered game below .. The first is to describe the tiered game... the game is played on a column of tiers... there are several natural points on each step .. two people playing a tiered game... each step moves several vertices (> = 1) in a group to the front .. at last, people who have no point to move will lose .. For example, this is the initial State of a tiered Game 2 1 3 2 4..

] [Status] [Discuss] Puzzle: Game problem. Need to use the Nim game, Nim game is to have n heap of stones, each can choose any stone from a heap of stones, the last person failed to take. For the Nim game there is a simple conclusion: a[1]^a[2]^a[3]. ^a[n]=0 will defeat at this time, anyway, the initiator win.Then this problem can actually be regarded as a

I haven't updated my blog for a long time. A while ago, I experienced my first job hopping, which is much harder than I thought. After all, it was the first job and it was quite sad to leave. The new job has just begun, and we hope everything will go well. This blog was written during May 1, and is officially posted today. It is a good habit to write a technical blog. I want to keep it! When I was in the previous job, I always wanted to try Flash/SSD

IntroducedThe Nim language does not restrict which specific coding style the developer uses,But for the sake of community development, we should follow a unified coding style when writing some standard libraries.This article will list a series of coding style guidelines for your reference.But it's worth noting that there are a number of exceptions that are inconsistent with these guidelines,Moreover, the Nim
