Science Fair Project - Square roots For a school science fair project, I need four or five square root algorithms to use. Googling gives sites like < with so many methods that I don't know how to narrow it down to four or five. I desire the most standard ones, that are simple to program in java. For example, the classic Newton's Iteration and the Bhaskara-Brouncker algorithm (The two i found so far) Also, I found Square Root Algorithm except I don't know the names of the algorithms used I need an answer urgently. Thanks in advance.

I'd go for:

1) Newton's Method

2) Midpoint Method

3) Secant Method

4) Taylor Series approximation

They're all similar in spirit in the sense that they all involve the derivative in some way and they're super simple to program because they're just math formulas you can just type in Java.
