A student exercise.

Choosing Boxes

You're given three boxes with values 17, 21, and 19.

Write a BQM and an Ocean program that returns the pair of boxes with the smallest sum. A starter file has been provided for you in choosing_boxes.py.

Remember:

You will need to choose a value for your Lagrange parameter and number of QPU reads. The autograder will test if your Lagrange parameter is large enough that the desired solution (boxes 17 and 19) has the smallest value.

For students in class submitting to our autograder:

Please index boxes 17, 21, and 19, using the string names 'box_17', 'box_19', and 'box_21', respectively, in your BQM. For example, if the coefficient on the linear term for Box 17 is 5, your program might set bqm.set_linear('box_17', 5).

Instructions

To write your program, please complete the following in choosing_boxes.py:

• Build your BQM in the get_bqm function, and set the Lagrange parameter.
• Find a good value numruns in the run_on_qpu function
• Complete the main function (bottom of the file) by defining a sampler, running your problem on that sampler, and looking at the results. "Looking at the results" may be as simple as printing out the sampleset object - it's up to you!
