The following cases are considered: digraphs with parallel edges, acyclic simple digraphs and general simple digraphs. The corresponding extremal digraphs are the tri\u2010chains, the (deficient) Fibonacci digraphs and (if our conjecture is true) the 3\u2010diamond strings, respectively. The similarity of these three families of digraphs is discussed. The related problem of digraphs with the maximum number of simple cycles for a given number of edges is considered too.<\/jats:p>","DOI":"10.1002\/net.3230170305","type":"journal-article","created":{"date-parts":[[2007,5,11]],"date-time":"2007-05-11T22:22:03Z","timestamp":1178922123000},"page":"295-305","source":"Crossref","is-referenced-by-count":3,"title":["Digraphs with maximum number of paths and cycles"],"prefix":"10.1002","volume":"17","author":[{"given":"Yehoshua","family":"Perl","sequence":"first","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2006,10,11]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCT.1968.1082837"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0012-365X(79)90131-6"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1137\/0204007"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1137\/0205007"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02760024"},{"key":"e_1_2_1_7_2","first-page":"211","volume-title":"Shortest paths in a network with two cost functions","author":"Perl Y.","year":"1978"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0012-365X(81)90063-7"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/j.1538-7305.1972.tb01925.x"}],"container-title":["Networks"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fnet.3230170305","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/net.3230170305","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,21]],"date-time":"2023-10-21T16:29:42Z","timestamp":1697905782000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/net.3230170305"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1987,1]]},"references-count":8,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1987,1]]}},"alternative-id":["10.1002\/net.3230170305"],"URL":"https:\/\/doi.org\/10.1002\/net.3230170305","archive":["Portico"],"relation":{},"ISSN":["0028-3045","1097-0037"],"issn-type":[{"value":"0028-3045","type":"print"},{"value":"1097-0037","type":"electronic"}],"subject":[],"published":{"date-parts":[[1987,1]]}}}
