Figure 6
The illustration displays a combined line and box plot with labeled axes, illustrating “Fitness (Deformation)” on the vertical axis, which ranges from 4.8 to 6.8 with an interval of 0.2. The horizontal axis is labeled “Generation,” ranging from 1 to 15 with an interval of 1. The box plots, outlined in blue, represent the spread of fitness values for each generation. Each box includes a red horizontal line, indicating the median fitness value for that generation, with the top and bottom “whiskers” showing the range of fitness values within 1.5 times the interquartile range. Data points that fall outside this range are marked as red crosses, representing outliers. The boxes in the early stages, from 1 to 3, and at generations 10 and 11 are larger than the other boxes. The green line with a square marker, labeled “min fitness per generation,” tracks the minimum fitness value for each generation, beginning slightly below 5.4 at generation 1 and gradually stabilizing around 5.1 at generation 2, then decreasing between 5 and 7 generations and reaching around 4.95, which remains constant till generation 15. Note: All numerical data values are approximated.LB path optimization results in terms of fitness per generation. Boxplot for each generation shows minimum, 1st quartile, median, 3rd quartile and maximum fitness values. The minimal values in each generation (green) provide results with the least deformation.
