SUMMARY

The discussion focuses on solving the Checkers Problem on an 8x8 board, where a checker starts in the fourth square of the bottom row and must reach the top row in seven diagonal moves. The solution involves calculating the number of paths leading to each square in successive rows, ultimately resulting in a total of 41 distinct paths to the top row. The participant initially miscalculated the paths as 103 but corrected it to 41 after further analysis.

PREREQUISITES
  • Understanding of combinatorial mathematics
  • Familiarity with recursive problem-solving techniques
  • Basic knowledge of checkers movement rules
  • Ability to visualize and manipulate grid-based problems
NEXT STEPS

All right...I've been at this all night, and any help whatsoever would be appreciated!

Problem-
An eight by eight square game board for checkers has a checker positioned in the fourth square of the bottom row. The checker is allowed to move one square at a time diagonally left or right to the row above. After seven moves the checker will be in the top row. How many different paths will lead to the top row?
 
Physics news on Phys.org
Start with the first row. Write in each square the number of paths that lead from the starting position to that square. (there will be seven zeroes and one one)

Use the numbers in the first row to figure out the number of paths from the starting square to each square in the second row.

Use the numbers in the second row to figure out the numbers in the third row.

Keep doing this until you've filled the last row, then just add up the numbers!
 
Danke! Very much! I owe you one! *runs off to solve problem*


EDIT: Final answer? 41 Wow...a lot smaller than what I was getting before...103...>_<
