From: utzoo!decvax!duke!ucf-cs!tim Newsgroups: net.unix-wizards Title: diff alg ref query Article-I.D.: ucf-cs.726 Posted: Mon Aug 2 16:49:14 1982 Received: Wed Aug 4 03:00:29 1982 To: tim Subject: diff algorithm Do you think that you could ask on the net if anyone knows of the original reference on the algorithm that diff uses ? The source says that it is "due to Harold Stone" but gives no other references. I thought I remembered a CACM number in source but I was wrong - the CACM # was for where they used a shellsort. I could check in the libarary using the name Stone but I thought it might be easier to ask on the net if you think thats reasonable. The reason I am interested in the algorithm is that I am unhappy with the source compare program I have now and would like to write a better one but the algorithm is not immediately apparent when reading the source for diffreg.c. Let me know what you think. Can anybody give an answer here? Tim Curry USENET: ucf-cs!tim ARPANET: tim.ucf-cs@udel-relay
