A Hybrid Metaheuristic for Multiple Runways Aircraft Landing Problem Based on Bat Algorithm
Algorithm 1
The pseudo-code of HBA for ALP.
(1) Initialize the ps, , bat population and other parameters; | (2) Construct initial bat population; // (3.3 Initialization construction) | (3) Assign landing time and evaluate each individual; // (3.2 Landing time assignment) | (4) repeat | (5) for :ps do | (6) Determine frequency ; | (7) Update each bat individual; | (8) end | (9) Assign landing time and evaluate each individual; // (3.2 Landing time assignment) | (10) if then | (11) Carry out swap local search operation; | (12) else | (13) Carry out LSI local search operation; | (14) end | (15) Assign landing time and evaluate each individual; // (3.2 Landing time assignment) | (16) Compute loudness of each individual by (12); | (17) for :ps do | (18) if then | (19) Carry out RB operation; // Runway balance operation | (20) else | (21) Assign each aircraft to a random runway; | (22) end | (23) end | (24) Assign landing time and evaluate each individual; // (3.2 Landing time assignment) | (25) until | (26) Output result and plot |
