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
