Based on the Bell polynomials scheme, this paper presents a Maple computer algebra program PDEBellII which can automatically construct the bilinear forms, bilinear Bäcklund transformations, Lax pairs and conservation laws of the KdV-type soliton equations. Some examples are given to verify the validity of our program.Program summaryProgram title: PDEBellIICatalogue identifier: AEQP_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEQP_v1_0.htmlProgram obtainable from: CPC Program Library, Queen’s University, Belfast, N.
