5. Integer linear programming problems are usually harder to solve compared with the linear programming problems. 6. [ ] In dynamic programming, the solutions in a later stage do not depend on the decisions from previous stages. 7. [ ] The least square method for estimating the unknown parameters in the simple linear regression is to minimize the sum of all the errors/deviations. 8. [ In the simple linear regression method, the minimization of the sum of squared errors is a minimization type of optimization formulation without any constraints
