Abstract The aim of this note is to obtain results about when the norm a projective tensor product strongly subdifferentiable. We prove that if $$X\widehat{\otimes }_\pi Y$$ X ⊗ ^ π Y ...

In the early 1970s, by work of Klee and Minty (1972) and Zadeh (1973), the Simplex Method, the Network Simplex Method, and the Successive Shortest Path Algorithm have been proved guilty of exponential worst-case behavior (for certain pivot rules). Since then, the common perception is that these algorithms can be fooled into investing senseless effort by ‘bad instances’ such as, e. g., Klee-Mint...
