In computer science, the research area of algorithms investigates formal procedures for solving computational problems, emphasizing correctness, efficiency, and resource optimization. It encompasses the design, analysis, and classification of algorithms across paradigms such as greedy methods, divide-and-conquer, dynamic programming, randomized algorithms, and approximation algorithms. Core topics include time and space complexity, worst-case and average-case analysis, lower bounds, and algorithmic optimality, often grounded in models like Turing machines or RAM. Algorithm research underpins fields such as data structures, cryptography, distributed systems, and machine learning, providing provably efficient methods and complexity guarantees crucial for both theoretical and applied computation.
About a century ago, scientists were struggling to reconcile what seemed like a contradiction in Albert Einstein's theory of general relativity.
