1.禁忌搜索算法：

基本原理：禁忌搜索是一种优化算法，用于在解空间中寻找最优解。它通过在搜索过程中禁止一定时间内重复访问已经访问过的解（通过禁忌表记录），以避免陷入局部最优解。

路径重连思想：路径重连是禁忌搜索的一种改进策略。当搜索过程中无法继续优化当前路径时，通过放弃一些先前搜索过的路径，重新启动搜索并尝试寻找新路径，有助于跳出局部最优解，更有可能达到全局最优解。

1. Taboo search algorithm:

Basic principle: Taboo search is an optimization algorithm used to find the optimal solution in the solution space. It prevents getting stuck in local optima by prohibiting repeated access to solutions that have already been accessed for a certain period of time during the search process (recorded through a taboo table).

Path reconnection idea: Path reconnection is an improved strategy for taboo search. When the current path cannot be further optimized during the search process, abandoning some previously searched paths, restarting the search, and trying to find a new path can help jump out of the local optimal solution and more likely achieve the global optimal solution.

2.防止早熟收敛：

早熟收敛问题：早熟收敛是指算法在搜索空间中提前陷入局部最优解，而无法进一步探索更优的解决方案的现象。

解决方法：为了防止早熟收敛，可以采用一系列策略，包括保持解的多样性、引入随机性、动态调整参数等，以确保算法在搜索过程中既能深入挖掘已知的有希望的解，又能广泛探索解空间的其他区域。

2. Prevent premature convergence:

Premature convergence problem: Premature convergence refers to the phenomenon where an algorithm is trapped in a local optimal solution in the search space in advance, and cannot further explore better solutions.

Solution: To prevent premature convergence, a series of strategies can be adopted, including maintaining solution diversity, introducing randomness, dynamically adjusting parameters, etc., to ensure that the algorithm can not only deeply explore known promising solutions during the search process, but also extensively explore other areas of the solution space.

3.全局最优解：

概念：全局最优解是在整个搜索空间中找到的最佳解决方案，它在问题的优化目标上达到最优。

目标：启发式算法的设计目标之一就是寻找全局最优解，而不仅仅是满足局部条件的最优解。通过路径重连思想和防止早熟收敛，算法更有可能在搜索空间中全面地找到最优解。

3. Global optimal solution:

Concept: The global optimal solution is the best solution found in the entire search space, which achieves the optimal optimization objective of the problem.

Objective: One of the design goals of heuristic algorithms is to find the global optimal solution, not just the optimal solution that satisfies local conditions. By using the idea of path reconnection and preventing premature convergence, the algorithm is more likely to comprehensively find the optimal solution in the search space.

4.实际应用：

禁忌搜索应用：禁忌搜索算法被广泛用于组合优化问题，如旅行商问题、调度问题等，以寻找问题的最优解。

优势：启发式算法因其灵活性和适应性而在实际应用中表现出色，能够处理复杂问题和大规模搜索空间。

4. Practical application:

Tabu search applications: Tabu search algorithms are widely used in combinatorial optimization problems, such as traveling salesman problems, scheduling problems, etc., to find the optimal solution to the problem.

Advantages: Heuristic algorithms perform well in practical applications due to their flexibility and adaptability, and can handle complex problems and large-scale search spaces.
