General solo undergraduate paper expectation, do I need to implement part of my paper or can I just describe the architecture and theory?

I’m working on a undergrad paper, not a top tier school that needs to be completed within a term.

I see deepmind papers always supported by rough implementations and results of what they’ve theorised. I understand that is the gold standard.

What is the general consensus on undergrad papers do they expect you to write code and implement some of what you’re theorising?

In my research I’ve came across papers like this which seem only theorised, without implementation:
