#1. Use basic strategies to get working board and apply bi-location tool.
#2. Choose G4{4579} - bi-location cell for 5,tri-location for 4 and 9.Need to
form ,progressively,the 3-element bi-location cell set G4H9B8.Only use basic strategies and only force the 1-cell to 3-cell run-out values(no contradiction values) until G4H9B8 = (4,9,3) which gives the solution. Other
3-cell bi-location set found was A1C8E2 = (2,5,9).
#3. Using this solution,with basic strategies,the following 3-cell solutions were found: A389 = (3,9,8), B6H79 = (5,3,9); no 2-cell or 1-cell were found.
