 Sep 24 comment Lagrange multipliers code runs forever Given the equality constraint g, why don't you simplify the problem to a two-variable one, Minimize[{f[x, y, 1 - x - y], x + y < 1, m1 > 0, m2 > 0, m3 > 0, x > 0, y > 0}, {x, y}], and furthermore solve for the first-order conditions instead of using brute-force minimisation? Sep 24 revised Lagrange multipliers implementation (beginner question) moved change of topic to other question Sep 24 comment Best practices, tools, and snippets for manipulating notebooks, cells, packages, and help access? @m_goldberg - thanks (and I'm going to delete all these comments now) Sep 22 revised Getting error Clip::ncompl from my trigonometric expression appended answer 95194 as supplemental Sep 17 revised Eigenvalues FEAST method - performance is very variable minor edits to clarify and hopefully attract an answer Sep 17 comment Eigenvalues FEAST method - performance is very variable Hello, this sounds like an interesting question. Obviously you can't post your actual data if it's that large, but have you managed to isolate the issue to a small matrix that has the same sensitivity of performance to small changes? Sep 17 comment Find the maximum Z in {(X + Y)==Z} using all the digits 0-9 only once @Masirius - please lower the temperature. You might find this useful: mathematica.stackexchange.com/help/closed-questions The fact is, experienced users are empowered to "close" questions if they do not feel the question is a good fit for the site. Please understand that people volunteer their time here to answer questions, and it is disrespectful of their time when other people post questions that show no effort of their own. I hope you have a good learning journey with Mathematica.
