  1. Island driven search As presented by shawnmurry

  2. What is Island driven search • Breadth first search that breaks a problem into smaller islands which are then solved individually in order to reach the main goal state

  3. Using Island driven search for sudoku • The islands of the sudoku problem are the individual numbers 1-9 used to solve a sudoku • The way that island driven search would try to solve this problem would be to try to fill in all the blanks that coincide to one number then move to solve the next number islands until the problem is solved

  4. Heuristic for island driven • Cost of a move = 9-X+Z • X= number of a particular number already on a board • Z= the number of conflicts of where you can legally place a number but could also maybe place another number

  5. Heuristic evaluation function • Total move to solve= (Y*K)-F • Y= total number of blanks on the board • K is the total number of conflicts in each square • F is the total number of solved islands + number of already filled in blanks

  6. Example sudoku
