Using the decision variables defined above, the linear algebraic expression for the objective function, in thousands of dollars, can be written as:

SocialNet is a social network company that seeks to improve its user experience and engagement. The company has identified five A/B test projects to consider running on its platform during the next quarter. Table 6 shows the estimated costs (in $ thousands) incurred by each A/B test project during each month of the next quarter. For example, Test 1 requires financing of $50,000 in month 1,$30,000 in month 2 , and $20,000 in month 3 . Table 6: Monthly Costs (in \$ thousands) for Each A/B Test Project The corresponding estimated net present values of revenue uplifts (in \$ thousands) for each project are shown in Table 7. For example, Test 1 has an estimated net present value of revenue uplift of $120,000. The revenue uplift is only realized at the end of the test.
