The art of IT problem-solving can be seen in the two phases of optimization problems: the problem formulation and solution. In the first phase, components include input variables, objective functions, and constraint functions. The second phase deals with the mathematical approach to find the solution using an optimization algorithm.

Input variables are the mutable components of the problem that can be adjusted for maximum efficiency. These can range from integer variables, real variables, and even Boolean variables. For instance, in expert advisors, variables could be the moving average period or the TP/SL ratio at entry.

Objective functions come into play when there are multiple goals for a given problem. The simplest method to combine these goals is by creating a weighted summation of each. In situations where there are multiple objective functions, it's important to normalize a...
