Computational complexity or algorithmic complexity refers to the amount of resource necessary to run the algorithm. In that regard, computation (execution time and scale with the problem size), measured by the number of required elementary operations. Computational problems can be classified based on their algorithmic complexity, how the resources are required to solve the problem. Computational complexity theory has the goal of classifying and comparing the practical difficulty of solving problems concerning finite combinatorial objects. Recognizing the underlying complexity of any algorithm is pivotal for understanding potentials and limitations. Computation is regarded as one of the most important pillars of science, and computational models in these scopes enable us to have opportunities which cannot be matched in real-world situations. Computational and mathematical models span across a broad array of application areas, which underscore the evident significance of to-the-point modeling to systems science. Considering all these factors, it is of utmost importance to attain the efficiency of information processing, and in that regard, computational complexity proves to be significant for analyses as problems increase in size and get more complex. Selecting the functions and algorithms for efficiency and solvability purposes is reliant on the classification and modeling based on the level of complexity concerned [Karaca, Y. (2023)].
Computational complexity concerns the estimation of how easily or how hard a problem can be solved on computational basis. Yet, the computational complexity would not provide the sole answer to the actual computation time that would elapse to solve a particular problem or instance of a problem since the actual implementations depend on certain factors including hardware and software. In another jargon, the computation of the complexity of a mathematical model involves the conducting of the analyses over the run time, which is concerned with the type of data determined and used in conjunction with the methods.
This ensures the possibility of examining the data applied, and this is dependent upon the capacity of the computer at work. In addition to these considerations, varying capacities of the computers have impact on the relevant results. What is more important is that the application of the method on the code step by step needs to be taken into consideration, which manifests that the definition of complexity evaluated over different data lends a broader applicability range with more convenience and realism due to the fact that the process depends on concrete mathematical foundations [Karaca, Y., et al. (2023)].
Computational complexity refers to the examination of the number of resources required for the task completion and performance. The Big-O notation is employed for the description of the computational complexity of an algorithm. In the case of an n2 complexity algorithm, the computational complexity is denoted by O(n2) in which n refers to the number of inputs. Accordingly, the Big-O notation is a mathematical formula providing the approximation or placing of an upper bound on the resource requirements, including both space and time (storage and memory, respectively), for an algorithm reliant on the size of the input [Karaca, Y. (2022)]. Attaining and maintaining accuracy, as a critical process, lies at the intersection of computational modeling and sciences as well as medicine, with the entailed integration of individualization and personalization of certain critical decision-making processes to improve the outcomes and reducing the burden.
In view of all these points, approaches based on theoretical framework and computational complexity as well as applied aspects of mathematics can ensure the optimization of implementing the processes related to the presumption, decision-making and prediction elements so that efficient management can be conducted and global optimal solutions can be yielded in chaotic, dynamic and nonlinear complex settings which manifest oscillation across time and space, which concurrently indicates time complexity [Karaca, Y., et al. (2022)].
