GCSE OCR Designing, creating and refining algorithms - OCR Pseudocode Algorithms are step-by-step plans for solving problems. Algorithms can be designed using pseudocode and flow diagrams.

Before designing an algorithm it is important to first understand what the problem is. Algorithms can be designed using pseudocode or a flowchart, and the standard notations of each should be known.

Researchers have developed a new algorithm to investigate systems with long-range interactions that were previously puzzling to experts.

The Shuffle algorithm pseudocode is lazy because it focuses only on the forward-traversing singly-linked list. It’s a reasonable design decision, but we pay a price for it in time complexity.
