These semigroups are affine semigroups, which in particular implies that they are finitely generated. For a given finite set of elements in [Formula: see text] we show how to deduce if the monoid spanned by this set is a generalized numerical semigroup and, if so, we calculate its set of gaps. Also, given a finite set of elements in [Formula: see text] we can determine if it is the set of gaps of a generalized numerical semigroup and, if so, compute the minimal generators of this monoid. We provide a new algorithm to compute the set of all generalized numerical semigroups with a prescribed genus (the cardinality of their sets of gaps). Its implementation allowed us to compute (for various dimensions) the number of numerical semigroups of higher genus than has previously been computed. <\/jats:p>","DOI":"10.1142\/s0219498821500791","type":"journal-article","created":{"date-parts":[[2020,2,11]],"date-time":"2020-02-11T10:51:45Z","timestamp":1581418305000},"page":"2150079","source":"Crossref","is-referenced-by-count":10,"title":["Algorithms for generalized numerical semigroups"],"prefix":"10.1142","volume":"20","author":[{"given":"Carmelo","family":"Cisto","sequence":"first","affiliation":[{"name":"Dipartimento di Scienze Matematiche e Informatiche, Scienze Fisiche e Scienze della Terra, Universit\u00e0 di Messina, Viale Ferdinando Stagno D\u2019Alcontres 31, 98166 Messina, Italy"}]},{"given":"Manuel","family":"Delgado","sequence":"additional","affiliation":[{"name":"CMUP, Departamento de Matem\u00e1tica, Faculdade de Ci\u00eancias, Universidade do Porto, Rua do Campo Alegre 687, 4169-007 Porto, Portugal"}]},{"given":"Pedro A.","family":"Garc\u00eda-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Departamento de \u0226lgebra and IEMath-GR, Universidad de Granada, 18017 Granada, Espa\u00f1a"}]}],"member":"219","published-online":{"date-parts":[[2020,3,23]]},"reference":[{"key":"S0219498821500791BIB001","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-41330-3"},{"key":"S0219498821500791BIB002","doi-asserted-by":"publisher","DOI":"10.1216\/JCA-2015-7-3-317"},{"key":"S0219498821500791BIB003","doi-asserted-by":"publisher","DOI":"10.1007\/s00233-007-9014-8"},{"key":"S0219498821500791BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpaa.2008.11.012"},{"key":"S0219498821500791BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpaa.2012.03.011"},{"issue":"1","key":"S0219498821500791BIB006","first-page":"49","volume":"27","author":"Cisto C.","year":"2019","journal-title":"Analele Univ. \u201cOvidius\u201d"},{"key":"S0219498821500791BIB007","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-35651-8"},{"key":"S0219498821500791BIB009","doi-asserted-by":"publisher","DOI":"10.1007\/s00233-015-9690-8"},{"key":"S0219498821500791BIB011","doi-asserted-by":"publisher","DOI":"10.1007\/s00233-017-9906-1"},{"key":"S0219498821500791BIB012","doi-asserted-by":"publisher","DOI":"10.1007\/s00233-012-9460-9"},{"key":"S0219498821500791BIB013","author":"Garc\u00eda-Garc\u00eda J.
