Shih, P.-H. and W.-S. Feng, An application of neural networks on channel routing problem, Parallel Computing 17 (1991) 229-240 The channel routing problem is to make interconnections among terminals located on opposite sides of a rectangular channel. This problem has been proven to be NP-complete.

## Abstract The objective of this study is to demonstrate that the channel flow routing techniques used in the Soil and Water Assessment Tool (SWAT) can be sometimes inappropriate for runoff simulation in small basins. Simulated hydrographs have a tendency to underestimate peak flows or may send a
We address the computational complexity of learning in the agnostic framework. For a variety of common concept classes we prove that, unless P ¼ NP; there is no polynomial time approximation scheme for finding a member in the class that approximately maximizes the agreement with a given training sam
## Abstract Let ℸ be the set of Gödel numbers Gn(__f__) of function symbols __f__ such that PRA ⊢ and let γ be the function such that We prove: (1) The r. e. set ℸ is m‐complete; (2) the function γ is not primitive recursive in any class of functions {__f__~1~, __f__~2~, ⃛} so long as each __f~i~
