Proximity matrix of solutions. Normalized frequency histogram of the elements of the proximity matrix built by computing the non-squared Euclidean distance ||log₁₀ K _i , log₁₀ K _j ||_{i, j = 1...n}, where {K _i } and {K _j } represent single solution parameter sets and n is the number of unknown model parameters. On the abscissa the distance values. For comparison we show also the distribution of the proximity matrix for a large set of randomly generated K vectors.
