Jacob’s stopping criterion for Moore-neighbourhood tracing requires position and direction to match. I checked before updating the direction, using the previous iteration’s leftover value, so the condition almost never fired — the tracer looped until the iteration cap, and the shoelace formula then closed the unclosed point list straight across the region.
Explain how any image is compressed into truecolor Unicode quadrant ANSI: 2 x 2 pixel blocks, minimum-error two-colour approximation, .ans files and browser-side privacy boundaries.
Optimise the eight queens search with bitmasks to cut the cost of state checks, with matching implementations in C and Python.
Work through K-means++ initialisation, iterative convergence and result analysis using Iris.csv, C source code, a flowchart and a visualisation.
Explain the state representation, conflict checks, recursive process and complete solution of the eight queens backtracking search in C and Python.
