Question 1
The robot IMSO–20 moves from the left side of the $5\times7$ board to the right side as shown on the left. It collects the scores on all cells that it passes. At the beginning, it may start in any cell of the first column from the left. Then it must move to the next column in the same row, one row above, or one row below, as shown on the right. Sketch a path for each route that gives (a) the lowest score (2 marks), (b) the highest score (4 marks).
