The first set of nine box plots is labeled “(a)” at the top. The horizontal axis for each graph represents different strategies, labeled from left to right as “Strategy 1”, “Strategy 2”, and “Strategy 3” in the first column, “Strategy 4”, “Strategy 5”, and “Strategy 6” in the second column, and “Strategy 7”, “Strategy 8”, and “Strategy 9” in the third column. The vertical axes represent three metrics: “M I T” for the first row, “T C O T M” for the second row, and “M R F I A” for the third row.
