There is a constant quest for the development and application of advanced techniques and methodologies. Among these, Metaheuristic Algorithms feature prominently. These algorithms function as high-level guiding strategies in optimization problems, particularly those concerned with machine learning and AI.

To put it simply, Metaheuristic Algorithms are intelligent computational methods used to solve difficult optimization problems that are not amenable to traditional optimization techniques. These algorithms are designed to explore the search space of a problem for the best possible, albeit not necessarily optimal solutions. Their aim is not to churn out perfect answers but rather to provide good enough solutions within a reasonable timeframe, even for complex, real-world problems.

Here are some key attributes of Metaheuristic Algorithms:

• Flexibility: Metaheuristic Algorithms are not problem-specific, meaning they can be applied to a wide range of optimization problems.
• Iterative Improvement: Most Metaheuristic Algorithms make iterative improvements on a single or a handful of initial solutions.
• Self-adaptive: They can adjust to the varying conditions of the problem to improve the solution as the search progresses.
• Use of randomness: While they are not purely random search methods, they do incorporate a degree of randomness in their search processes.
• Hybridization Capable: The algorithms can be combined with other algorithms to yield more effective methods.

Metaheuristic Algorithms have carved a niche in the field of AI due to the following inherent advantages:

• Problem Independence: Their flexibility sets them apart. Unlike many traditional optimization methods that are designed for specific problems, Metaheuristic Algorithms are problem-independent and have wide applicability across diverse optimization problems.
• Efficacy: They’re known for their ability to provide good solutions quickly, even in complex, high-dimensional search space, which is often a challenge for other optimization methods.
• Global Optimization: Unlike local search techniques, Metaheuristic Algorithms are designed to escape local optima and aspire for global optimality, making their solutions more trustworthy.
• Simplicity: Most Metaheuristics are conceptually simple and easy to understand and implement.

With its multiple perks, Metaheuristic Algorithms nonetheless have their limitations:

• Parameter setting: One of the challenges is determining the suitable parameter settings for a particular problem, which can significantly affect the performance of the algorithm.
• Convergence: While they aspire for global optimality, proving their convergence to global optimum is often a daunting task.
• Computation Time: If poorly implemented, they may require more computation time than other methods.
• Lack of Guarantee: Most Metaheuristic Algorithms provide no guaranty about the quality of the found solution.

In AI applications, Metaheuristic Algorithms often serve as an excellent tool for optimizing machine learning models, with their applications ranging from clustering, feature selection, to hyperparameter tuning.

Implementing Metaheuristic Algorithms demands a detailed understanding of the problem, careful selection of suitable algorithm or algorithm variants, and a clear setting out of parameters. It's also crucial to know the computational resources available before employing these algorithms.

In conclusion, Metaheuristic Algorithms, with their flexibility and wide application, have become an integral part of AI optimization problems. They add substantial value by offering reasonable solutions to complex problems within a practical timeframe. Despite their limitations, Metaheuristic Algorithms’ adoption in AI is set to increase due to the growing complexity of optimization problems and the considerable benefits they offer. The key lies in an understanding of their dynamics and an effective harnessing of their potential to solve complex optimization problems.
