Application of Chaos-variables Based Fish-net Algorithm in Slope Stability Analysis

To cope with the low searching efficiency of original fish-net algorithm for multivariable optimization problems,the formulation of fish-net algorithm in combination with chaos variables which can simulate the two different nets(smaller density net and larger density net) used in original fish-net algorithm was put forward.The smaller density net is mainly functional for the exploration of unknown solutions,whereas the larger density net is mainly functional for the exploitation of found solutions.The fish-net algorithm based on chaos variables was adopted to locate the minimum safety factor for typical slope.The implementation of fish-net algorithm based on chaos variables was described.The comparative studies with the published reports and the results obtained by original fish-net algorithm show that the proposed combinatorial algorithm is more efficient than original one for road slope design.
