WebA good reference to get started from the algorithmic point of view is Chapter 3 of Cremona's Algorithms for Modular Elliptic Curves. It contains a good deal of pseudocode which explains how Cremona's C++ package mwrank computes rational points on elliptic curves. Some of the more intricate details, such as second descents are left to Cremona's ...
