Summary of average extracted errors of parameters for various tissue types for the top 3 optimized solutions.

Positive values indicate an over-estimation of the extracted parameters while negative values indicate an under-estimation of the parameters. [THb]: total hemoglobin; [βc]: β-carotene; s’>: reduced scattering coefficient; A: adipose tissue; FG: fibroglandular; M: malignant tissue; ES8λ: semi-evenly spaced 8 wavelengths (400, 420, 440, 470, 500, 530, 570, 600 nm).
