Please refrain from making unconstructive edits to Wikipedia, as you did at Betty Boop. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. Kleuske (talk) 16:48, 20 May 2019 (UTC)

Please refrain from making test edits in Wikipedia pages, such as those you made to Mathematical optimization, even if you intend to fix them later. Your edits have been reverted. If you would like to experiment again, please use the sandbox. Thank you.  Orville1974  (talk) 22:59, 3 June 2019 (UTC)
