Claude and Gemini compete in AI coding challenge to solve a complex weighted knight's tour optimization problem on day 8.

The eighth challenge is a variant of the classic knight's tour problem with added complexity from weight mechanics

Knights must visit every square on a rectangular board exactly once while accumulating load based on square weights

The cost of each move equals the knight's current load, with charges assessed upon departure rather than arrival

The final square's weight does not contribute to the total cost since no move departs from it

This weighted variant requires optimization beyond the traditional knight's tour, testing AI problem-solving capabilities
