Types of Root Finding Algorithms
Root-finding algorithms can be broadly categorized into Bracketing Methods and Open Methods.
- Bracketing Methods: This method starts with an interval where the function changes sign, ensuring that a root lies within this interval. These methods iteratively reduce the interval size to home in on the root.
- Open Methods: This starts with one or more initial guesses that do not necessarily bracket the root. These methods can converge more quickly but do not always guarantee convergence.
Root Finding Algorithm
Root-finding algorithms are tools used in mathematics and computer science to locate the solutions, or “roots,” of equations. These algorithms help us find solutions to equations where the function equals zero. For example, if we have an equation like f(x) = 0, a root-finding algorithm will help us determine the value of x that makes this equation true.
In this article, we will explore different types of root finding algorithms, such as the bisection method, Regula-Falsi method, Newton-Raphson method, and secant method. We’ll explain how each algorithm works, and how to choose the appropriate algorithm according to the use case.
