Registry layers and naming

Purpose

The Approach Registry is a database that organizes algorithms into levels. It helps the system find the right tool for your task. It also makes sure that you can use many different names for the same algorithm.

Why it exists

Coding is personal. One person might call a tool "union_find" while another calls it "dsu". The registry ensures the system understands both. It also keeps simple tools separate from elite ones to avoid confusion.

How it works

The algorithms are sorted into five levels based on their complexity.

1. Level 1: Atoms. Basic tools for reading and writing data.
2. Level 2: Standard. Common tools for sorting and searching.
3. Level 3: Patterns. Solutions for paths and classic logic problems.
4. Level 4: Specialized. Advanced tools for segments and math flows.
5. Level 5: Elite. The most difficult competitive tools like Mo's algorithm.

Intuition

Think of the registry like a library. The levels are the different sections, from children's books to advanced science. The name resolution is like the computer catalog. It doesn't matter if you search for the author's real name or their pen name, the catalog will lead you to the same book.

Name resolution steps

1. Direct match. The system looks for the exact name you typed.
2. Mapping. If no match is found, it checks a list of alternative names.
3. Fuzzy search. If it is still lost, it looks for names that are similar and suggests the best choice.
