Spatial-Temporal Data Integration Modeling and Dynamic Simulation of Coal-Rock Dynamic Disasters

Algorithm 1

This algorithm optimizes SVM parameters.

(1)	% objective function
(2)	fun = @getobjValue; % fitness function
(3)	% number of optimization parameters (c, g)
(4)	dim = 2;
(5)	% the lower limit of the optimization parameter
(6)	lb = [10^-1, 2^-5];
(7)	ub = [10^1, 2^4];
(8)	pop = 10; % number of sparrows
(9)	max_iteration = 20; % the maximum number of iterations
