title: Optimization algorithms that does not depend on initial solution
body: <p>I know some optimization algorithms, such as hill-climbing, simulated-annealing, genetic algorithm.</p>
  
  <p>All of the three I mentioned depend on the initial solutions, i.e., the initial solutions may have a great impact on the quality of the final optimal solution.</p>
  
  <p>I wonder if there are any optimization algorithms that don't depend on initial solutions, at least not as much as these three.</p>
  
  <p>Thanks.</p>
