Hi Math Group, I would like to visualize the set of iterations that the built-up function FindMinimum carry out searching the minimum. For exemple when I write: FindMinimum[x\^4 + 3 \( x\^2\) y + 5 y\^2 + x + y, {x, 0.1}, {y, 0.2}] I would like to see the the values of x and y got for every iteration. With the Trace function I've got the following empty output: {FindMinimum[x + 3 x y + 5 y + x + y, {x, 0.1}, {y, 0.2}], {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {$MessageList = {}, {}}, {x =. , Null}, {y =. , Null}, {-0.832579, {x -> -0.886326, y -> -0.335672}}} How can I do? kind regards Umby
