{"quality_controlled":"1","abstract":[{"lang":"eng","text":"The partial representation extension problem is a recently introduced generalization of the recognition problem. A circle graph is an intersection graph of chords of a circle. We study the partial representation extension problem for circle graphs, where the input consists of a graph G and a partial representation R′ giving some predrawn chords that represent an induced subgraph of G. The question is whether one can extend R′ to a representation R of the entire graph G, that is, whether one can draw the remaining chords into a partially predrawn representation to obtain a representation of G. Our main result is an O(n3) time algorithm for partial representation extension of circle graphs, where n is the number of vertices. To show this, we describe the structure of all representations of a circle graph using split decomposition. This can be of independent interest."}],"date_updated":"2023-08-24T14:30:43Z","isi":1,"ec_funded":1,"publication_status":"published","title":"Extending partial representations of circle graphs","intvolume":"        91","publisher":"Wiley","external_id":{"isi":["000485392800004"],"arxiv":["1309.2399"]},"date_published":"2019-08-01T00:00:00Z","language":[{"iso":"eng"}],"issue":"4","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_created":"2018-12-30T22:59:15Z","oa_version":"Preprint","year":"2019","main_file_link":[{"url":"https://arxiv.org/abs/1309.2399","open_access":"1"}],"month":"08","publication_identifier":{"issn":["03649024"]},"article_type":"original","_id":"5790","author":[{"last_name":"Chaplick","full_name":"Chaplick, Steven","first_name":"Steven"},{"id":"39F3FFE4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8485-1774","last_name":"Fulek","full_name":"Fulek, Radoslav","first_name":"Radoslav"},{"last_name":"Klavík","full_name":"Klavík, Pavel","first_name":"Pavel"}],"day":"01","article_processing_charge":"No","doi":"10.1002/jgt.22436","oa":1,"citation":{"short":"S.
