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
