Abstract
This paper aims to explore the definition and characteristics of the Christmas tree problem and its application in mathematical modeling and combinatorial optimization methods. First, the basic concepts and characteristics of the Christmas tree problem are summarized, and the research status and application background in related fields are briefly reviewed. Then, the mathematical model of the Christmas tree problem is deeply constructed, the definition of the ob jective function, constraints and variables is defined, the decision-making idea is expounded, and the key impact of parameter tuning on the algorithm performance is analyzed. In the application of combinatorial optimization method, this paper discusses the specific application of exhaustive search algorithm, greedy algorithm and genetic algorithm in the Christmas tree problem. The exhaustive search algorithm provides a comprehensive perspective to solving the problem, while the greedy algorithm shows advantages in specific situations with its high efficiency, while the genetic algorithm provides a powerful global search ability for the solution of complex Christmas tree problems by simulating the natural evolution process. The discussion of these methods not only enriches the solving strategy of the Christmas tree problem, but also provides new ideas and enlightenment for the combinatorial optimization problem in related fields.
