There has been a lot of speculation over the years about the quality of the optimization solvers in SAS/OR, in particular the mixed integer linear optimization (MILP) solver. Measuring the performance of optimization solvers and comparing different solvers on a test set is a crucial part of modern optimization solver development.
Let me make this clear right from the start: I needed to answer 44 of the 62 exam questions correctly to earn my BASE SAS Programmer certification, and I got exactly 44 right. No margin of error. I never thought I’d be proud of a 70%, but I’m more than
Displaying nicely rendered axis values reduces clutter and makes the graph more readable. With SAS 9.4, we added the ability for splitting x-axis tick values on white space to create a nice and readable x-axis as shown in the graph on the right. It is always a challenge to fit
