What is the minimum string length required to code the variable range (-3, 5) with an accuracy of 0.0001? An optimization problem has three design variables that are to be coded in binary strings. The range of variables is (-100, 50), (0, 1), and (3, 7) and the accuracy required is 0.01, 0.00001, and 0.001 respectively. Compute the minimum length of the string required.
