线性规划(linear programming)和整数规划(integerprogramming)的主要区别是决策变量的约束不同,其中线性规划的变量为正实数,而纯整数规划的变量为正整数。如果决策变量中一部分为整数,另一部分可以不取整数,则该问题为混合整数规划 (mixedinteger linear programming)。线性规划和整数规划都可以视为混合整数规划的特例,用矩...

每个基本对象的类型都有一个S3类名称。比如integer,numeric, character, logical, list和data.frame都属于S3类。 S3类内部是一个list,append某个list类名称,就能成为该类。list里面的内容就是我们所说的属性. 首先创建一个list 代码语言:javascript 复制 >dnaseq=list(seq="ATGC",length=nchar("ATGC"))>dnaseq ...

Mixed Integer Linear Programming in RTheussl, Stefan
The notion of symmetry is defined in the context of Linear and Integer Programming. Symmetric linear and integer programs are studied from a group theoretical viewpoint. We show that for any linear program there exists an optimal solutio... R Bödi,K Herr - 《Arxiv Preprint Arxiv》 被引量...
Rulp is an easy to use Ruby DSL for generating linear programming and mixed integer programming problem descriptions in the LP file format. The [.lp] file format can be read and executed by most LP solvers including coin-Cbc, Scip, GLPK, CPLEX and Gurobi. Rulp will execute and parse the...

Integer—whole numbers. Character—a letter, number, or symbol, or any combination of them, enclosed in regular or single quotation marks. Factor—categories from a predefined set of possible values, often with an intrinsic order. Logical—the Boolean valuesTRUEandFALSE, represented under the hood...
1) Explain in words a (very) trivial coloring algorithm for an undirectedgraph with n nodes. Give an upper bound on the number of colorsneeded for your coloring algorithm.(2) Formulate the chromatic number problem of a graph G = (V, E),V = {1, . . . , n} as an integer linear...
