This is the second post (here’s the first one) about an approach to introducing the derivative to calculus students that is counter to what I’ve seen in textbooks and other traditional treatments of ...

lems with a certain class of piecewise linear loss functions. The problem of computing the i\ regularization path for a piecewise linear loss can be formalized as a parametric linear programming ...

A theory of plasticity is considered in which the yield function is a piecewise linear function of the stresses, the flow law is based on the plastic potential, and the strain-hardening is isotropic ...
