Sure! Here's the MATLAB code for the Golden Sine algorithm:
```matlab
function golden_sine_algorithm()
% Set parameters
iterations = 100; % Number of iterations
phi = (1 + sqrt(5)) / 2; % Golden ratio
% Initialize search range
a = 0;
b = phi;
% Main loop
for i = 1:iterations
% Calculate new points
x1 = b - (b - a) / phi;
x2 = a + (b - a) / phi;
% Evaluate function at new points
f_x1 = objective_function(x1);
f_x2 = objective_function(x2);
% Update search range based on function values
if f_x1 < f_x2
b = x2;
else
a = x1;
end
end
% Calculate minimum point
min_point = (a + b) / 2;
% Display results
disp('Minimum point:');
disp(min_point);
disp('Objective function value at minimum point:');
disp(objective_function(min_point));
end
function value = objective_function(x)
% Define your objective function here
value = sin(x);
end
```
This code implements the Golden Sine algorithm in MATLAB. The algorithm searches for the minimum value of a given objective function within a specified search range. The algorithm is based on the golden ratio and iteratively updates the search range until convergence.
