Tim Meagher Fall 2010 Abstract We consider a number of related results taken from two papers – one by W. Lin [1], and the other D. C. Fisher[2]. These articles treat
Some Concrete Results • If G connected, Error = OpV . • For grids of size × n, optimal Error = Θp2n. Until c ≤ 2, then Opn optimal. • √n× √ n grid: We recover…
