Integer Programming

The problem of integer programming (IP) refers to a problem in which some or all variables must take integer values. In the case when the constraints and the objective function are linear dependence problem is called an integer linear programming problem. Otherwise, if at least one non-linear dependence will be, it will be the integer nonlinear programming problem.
Of particular interest to the problems of the IP due to the fact that in many practical problems, we need to find an integer solution due to a discrete series of values ​​of the variables. In the

- Construct a relative frequency histogram for the chest circumference data, using classes based on a single value.
Looking at the table we first have to get the total frequency by summing the values in that specific column. The table is filled according to the following procedure. You can check out the excel file attached alongside that show numerical workings.
Arrange the value in the order presented and then multiply each frequency and chest size per row to get the product of frequency and chess size. When you add the entire column of the results and divide by the
