A note on Dodgson's determinant condensation algorithm
Recently, the Dodgson's determinant condensation algorithm was revisited in
many papers [College Math. Journal 42(1)(2011): 43--54, College Math. Journal
38(2)(2007): 85--95, Math Horizons 14(2)(2006): 12--15},etc.]. This method is
attractive, but there also exist some shortcomings. In this paper, a symbolic
algorithm and the corresponding problems are discussed to overcome these
shortcomings. Numerical experiments show that this symbolic modified algorithm
has highly sensitivity on initial configuration of the matrix in condensation
process.Comment: 10 pages, 3 figure
