Overview for Simulated Annealing Algorithm

1. Define the Objective Function: The objective function which is to be reduced must be described.
2. Set Parameters: We focus on initializing parameters such as terminating criteria, preliminary temperature, cooling schedule, etc.
3. Initialization: It is advisable to begin with a primary approach.
4. Iterative Improvement:

• A neighbouring approach has to be produced.
• Our team aims to assess the novel solution.
• Typically, on the basis of a possibility which relies on the temperature and variation in objective function values, our team determines whether to approve the novel approach.
• On the basis of the cooling schedule, we intend to upgrade the temperature.

5. Stopping Criteria: It is appreciable to terminate the operation if the temperature is adequately less or when the extreme number of iterations is attained.

Instance Code

The following is a basic instance to apply the Simulated Annealing method in MATLAB:

function [bestSol, bestVal] = simulatedAnnealing(objFunc, x0, initialTemp, coolingRate, maxIter)

% Simulated Annealing Algorithm

%

% Inputs:

% objFunc – Objective function to minimize

% x0 – Initial solution

% initialTemp – Initial temperature

% coolingRate – Rate at which temperature decreases

% maxIter – Maximum number of iterations

%

% Outputs:

% bestSol – Best solution found

% bestVal – Objective function value of the best solution

% Initialize

currentSol = x0;

currentVal = feval(objFunc, currentSol);

bestSol = currentSol;

bestVal = currentVal;

temp = initialTemp;

% Main loop

for iter = 1:maxIter

% Generate a neighboring solution

newSol = currentSol + randn(size(currentSol));

newVal = feval(objFunc, newSol);

% Accept the new solution with a certain probability

if newVal < currentVal || rand < exp((currentVal – newVal) / temp)

currentSol = newSol;

currentVal = newVal;

% Update the best solution found

if newVal < bestVal

bestSol = newSol;

bestVal = newVal;

end

end

% Decrease the temperature

temp = temp * coolingRate;

% Display progress

fprintf(‘Iteration %d: Best Value = %.4f\n’, iter, bestVal);

% Stop if temperature is too low

if temp < 1e-10

break;

end

end

end

% Example usage:

objFunc = @(x) (x(1) – 3)^2 + (x(2) + 1)^2; % Objective function

x0 = [0, 0]; % Initial solution

initialTemp = 10; % Initial temperature

coolingRate = 0.95; % Cooling rate

maxIter = 1000; % Maximum number of iterations

[bestSol, bestVal] = simulatedAnnealing(objFunc, x0, initialTemp, coolingRate, maxIter);

disp(‘Best Solution:’);

disp(bestSol);

disp(‘Best Objective Value:’);

disp(bestVal);

Description

1. Define the Objective Function:

• The function to be decreased is objFunc. It is considered as a basic quadratic function in this instance.

2. Set Parameters:

• initialTemp: This parameter indicates the preliminary temperature which is initialized to 10.
• coolingRate: Generally, it specifies the rate at which temperature reduces. It is fixed to 0.95.
• maxIter: It denotes the extreme number of iterations that is initialized to 1000.

3. Initialization:

• Initially, it is significant to begin with preliminary approach x0.

4. Iterative Improvement:

• Through appending an occasional perturbation to the existing approach, we aim to produce a neighbouring approach.
• It is appreciable to assess the novel approach.
• On the basis of the Metropolis measure, we determine whether to approve the novel approach.
• Through the utilization of the cooling schedule, our team aims to upgrade the temperature.

5. Stopping Criteria:

• If the temperature is adequately less or when the maximum number of iterations is attained, we plan to terminate the process.

Instance Usage

In this instance, the instance function is objFunc, which is examined as a basic quadratic function that is (x1−3)2+(x2+1)2(x_1 – 3)^2 + (x_2 + 1)^2(x1−3)2+(x2+1)2. We focus on setting the initial solution as [0,0][0, 0][0,0]. With a cooling rate of 0.95 and an initial temperature of 10, the algorithm executes for a maximum of 1000 iterations.

At each execution, the development of the optimal object value is efficiently indicated by this algorithm. The optimal solution and its significant objective value ought to be exhibited in the final analysis.
