title: Scaling of objective function in optimization problems
body: <p>In a lot of optimization algorithms I have seen that they use a scaling factor to scale the objective function. I dont understand what is the reason behind this. Why do we need scaling of objective function in optimization algorithms? Does it work without scaling. Logically it should work but I am a litte bit confused now.</p>
  
  <p>I hope you can answer me and thank you indeed</p>
