Figure 1From: Listing all sorting reversals in quadratic timeTwo breakpoint graphs. The breakpoint graphs for a) π = (-1 2 4-5 6 8-7-3) and b) π ○ ρ(6, 8). The direction that reality edges are traversed on a tour of the cycles is labeled with arrows. ρ(6, 8) is an unsafe reversal on π.Back to article page
