title: is there any direct way in C# to optimize a math function or minimize a parameter in an expression?
body: <p>I am trying to implement an algorithm in C# that has some math function inside like :</p>
  
  <p>Minimize a  ||xu( i )  -  ∑j aj( i ) bj ||2  +  β || a( i ) ||1</p>
  
  <p>but I'm not sure if there is any direct method in C# for optimizing and I couldn't find any thing in forums , or maybe you can offer  any suggestion to solve this optimization problem in C# !?   </p>
