Chapter number or note title: Linear Programming Algorithms

Error description: The following equivalence is false:

The Weak Duality Theorem implies that the value of every feasible basis is less than
or equal to the value of every locally optimal basis; equivalently, every feasible vertex
is higher than every locally optimal vertex.

Suggested fix (if any): It should be:

The Weak Duality Theorem implies that the value of every feasible basis is less than
or equal to the value of every locally optimal basis; equivalently, every feasible vertex
is no lower than every locally optimal vertex.
