Comparison of Root Finding Methods
The comparison between the root finding methods are being showed below, on the basis of advantages and disadvantages.
Method | Description | Advantage | Disadvantage |
---|---|---|---|
Bisection Method | It divides interval in half, and guarantees convergence | Simple and faster method | Slow convergence |
False Position Method | It uses linear interpolation, faster than bisection | It maintains bracketing, faster than bisection | It may fail due to roundoff errors |
Newton’s Method | It uses function and derivative, fast convergence | It is a quadratic convergence, works in higher dimensions | It may not converge if initial guess is far |
Secant Method | It is a derivative-free variant of Newton’s, simpler | It doesn’t require derivative, faster than bisection | Slower convergence (order ~1.6) |
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.
