Bisection Method Pseudocode

Earlier in Bisection Method Algorithm, we discussed about an algorithm for computing real root of non-linear equation using Bisection Method. In this tutorial we are going to develop pseudocode for Bisection Method so that it will be easy while implementing using programming language.

Complete Pseudocode for Bisection Method

1. Start

2. Define function f(x)

3. Input 
	a. Lower and Upper guesses x0 and x1
	b. tolerable error e
	
4. If f(x0)*f(x1) > 0
	print "Incorrect initial guesses"
   	goto 3
   End If

5. Do 
	x2 = (x0+x1)/2
	
	If f(x0)*f(x2) < 0
		x1 = x2
	Else
		x0 = x2
	End If
		
   while abs(f(x2) > e
   
6. Print root as x2

7. Stop
