I've made a number of updates to my MathProg web page ( http://www3.nd.edu/~jeff/mathprog/mathprog.html) based on feedback received from students and others. The changes include --
-- the Open and Save dialogs now allow you to store MathProg models on Dropbox, Box, or Google Drive in addition to your local computer. This makes is easy to share models with others or to integrate into course management systems. -- the "Create Link" button embeds MathProg models directly into web links that can be cut and paste into web documents. Clicking on the link will open the model in the editor ready to run. This feature is useful for emailing models, or to include links from classroom presentations, web pages, etc. Here's an example giapetto.mod<https://www3.nd.edu/~jeff/mathprog/mathprog.html?model=%23%20Example%3A%20giapetto.mod%0A%23%0A%23%20Find%20the%20optimal%20solution%20maximizing%20Giapetto's%20profit%0A%0A%23%20Decision%20variables%0Avar%20x1%20%3E%3D0%20integer%3B%20%20%23%20soldier%0Avar%20x2%20%3E%3D0%20integer%3B%20%20%23%20train%0A%0A%23%20Objective%20function%0Amaximize%20profit%3A%203*x1%20%2B%202*x2%3B%0A%0A%23%20Constraints%0As.t.%20Finishing%3A%201.85*x1%20%2B%20x2%20%3C%3D%20100%3B%0As.t.%20Carpentry%3A%20x1%20%2B%20x2%20%3C%3D%2080%3B%0As.t.%20Demand%3A%20x1%20%3C%3D%2040%3B%0A%0Asolve%3B%0A%0Adisplay%20x1%2C%20x2%2C%20profit%3B%0Adisplay%20Finishing%2C%20Carpentry%2C%20Demand%3B%0A%0Aend%3B%0A> . -- the interface has been simplified by removing the LP/MIP switch, and the exercises menu. Beginning students found this a bit confusing. -- tooltips have been added for a number of items. I'll be doing some more cleanup in the next few days. This will include better handling of the output panels with options to download into spreadsheets. Thanks again to Henri Gourvest for the terrific glpk.js. Jeff
