Hill climbing is an optimization technique for solving computationally hard problems. It is best used in problems with “the property that the state description itself contains all the information needed for a solution” (Russell & Norvig, 2003).  The algorithm is memory efficient since it does
Abstract: The paper proposes artificial intelligence technique called hill climbing to find numerical solutions of Diophantine Equations. Such equations are important as they have many applications in fields like public key cryptography, integer factorization, algebraic curves, projective curves and data dependency in super computers.
Artificial Intelligence (AI) began before the arrival of electronics; it began when philosophers and mathematicians such as George Boole (rightly regarded as one of the founding fathers of computing and information technology (1815–1864)) and others established the principles, which came to be used as the basis for AI logic. In 1943, AI started with the beginning of the invention of the

Rule Based Systems and Search Notes 1. Rule-Based Systems: Backtracking: When we talk about DFS or DFS variants (like Hill Climbing) we talk about with or without “backtracking”. You can think of backtracking in terms of the agenda. If we make our agenda size 1, then this is equivalent to having no backtracking. Having agenda size > 1 means we have some partial path to go back on, and

Hill climbing can often produce a better result than other algorithms when the amount of time available to perform a search is limited, such as with real-time systems. PROBLEMS: Local maxima: A surface with two local maxima. (Only one of them is the global maximum.) If a hill-climber begins in a poor location, it may converge to the lower maximum. A problem with hill climbing is that it will
