Figure 15From: An ant colony optimisation algorithm for the 2D and 3D hydrophobic polar protein folding problemImpact of parameter settings on ACO-HPPFP-3 performance in 2D and 3D: pheromone persistence. Effect of the pheromone persistence parameter, ρ, on the average CPU time required for obtaining minimal energy conformations of Sequence S1-8 in 2D (length 64, left side) and Sequence S2-5 in 3D (length 48, right side).Back to article page
