It is tedious to enumerate all of the subgroups of a symmetric group, such as \(S_4\). And I wrote a program to automate it.
In the 3rd Lab of CS:APP: Attack Lab, the distributed binary ctarget
is too old and it cannot normally run on today's Ubuntu 22.04. I tried to analyze the problem and raise a resolution for that.
WeChat is a useful software to communicate with others. Unfortunately, WeChat Official does not provide Linux version. DoChat is a great alternative.
OT:除米什拉-格赖斯算法和贪心算法外,边染色和点染色问题还有很多其它算法,请为每种问题调研至少1种精确算法(暴力算法不在调研范围内),结合例子介绍算法的设计与分析。
OT:在独立、覆盖和支配的基础上,形成了很多扩展的优化问题,例如最小权完美匹配问题(Minimum-Weight Perfect Matching)、最小连通支配集问题等,请调研至少2种问题(其中至多1种来自上述例子,二分图最大匹配问题等仅限制原始问题输入的问题不在调研范围内),讨论适用场景,形式化描述问题,为每种问题结合例子介绍至少1种算法的设计与分析。
OT:除MS和MAX-CUT外,近似算法还可用于解决其它问题,例如SCP(JH算法4.3.2.11)、SKP(JH算法4.3.4.1和4.3.4.2)等,请调研至少2种近似算法(其中至多1种来自上述例子,图上的优化问题不在调研范围内),结合例子介绍算法的设计与分析,重点阐述近似比的证明过程。
OT:除IP外,广义的“松弛-修正”思想还可用于解决其它问题,例如TSP的松弛修正算法、最短超串问题的松弛修正算法等,请调研至少2种算法(其中至多1种来自上述例子),结合例子介绍算法的设计与分析,重点阐述其中的“松弛-修正”思想。
OT:除MAX-SAT和TSP外,分支定界和局部搜索算法还可用于解决其它问题,请为每种算法调研至少1种可以解决的问题,结合例子介绍算法的设计与分析。
