Class 3, C&O 367



  1. positive and negative definite matrices (relation to optimization on Rn)
    1. leading principal minor tests for positive definite matrices (Be aware that the book has the wrong definition for principal minors, i.e. their definition should be called leading principal minors.)
    2. sufficient optimality conditions (tests) for local minima
    3. min f(x) is equivalent to -max-f(x)
    4. examples on quadratic functions
    5. examples of saddle points
