Choice design variablesThe design variables we have considered for optimization define dimensions or angles or in more general terms the magnitude of a variable or the number of items.For laminate design, we will also run into choice design variables that will define which of several options we will choose.For Example 4.1.1, we had to choose between three laminates and this is formulated with choice design variables in Example 4.1.2.Later, the main use would be to choose ply angles from a limited set of 0, 90, 45 or -45.
