Arguments

arg1: The first Expression in the minimum operation.
arg2: The second Expression in the minimum operation.
...: Additional Expression objects in the minimum operation.
object: A MinElemwise object.
values: A list of numeric values for the arguments
idx: An index into the atom.

Methods (by generic)

to_numeric(MinElemwise): The elementwise minimum.
sign_from_args(MinElemwise): The sign of the atom.
is_atom_convex(MinElemwise): The atom is not convex.
is_atom_concave(MinElemwise): The atom is not concave.
is_atom_log_log_convex(MinElemwise): Is the atom log-log convex?
is_atom_log_log_concave(MinElemwise): Is the atom log-log concave?
is_incr(MinElemwise): The atom is weakly increasing.
is_decr(MinElemwise): The atom is not weakly decreasing.
is_pwl(MinElemwise): Are all the arguments piecewise linear?
.grad(MinElemwise): Gives the (sub/super)gradient of the atom w.r.t. each variable

Slots

arg1: The first Expression in the minimum operation.
