We model such a “compromised” drawing by a piecewise linear map φ:G → ℝ. We wish to perturb φ by an arbitrarily small ε>0 into a proper drawing (in which the vertices are distinct points, any two edges intersect in finitely many points, and no three edges have a common interior point) that minimizes the number of crossings. An ε-perturbation, for every ε>0, is given by a piecewise linear map (Formula Presented), where with ||·|| is the uniform norm (i.e., sup norm). We present a polynomial-time solution for this optimization problem when G is a cycle and the map φ has no spurs (i.e., no two adjacent edges are mapped to overlapping arcs). We also show that the problem becomes NP-complete (i) when G is an arbitrary graph and φ has no spurs, and (ii) when φ may have spurs and G is a cycle or a union of disjoint paths."}],"department":[{"_id":"UlWa"}],"publisher":"Springer","type":"conference","alternative_title":["LNCS"],"quality_controlled":"1","doi":"10.1007/978-3-030-04414-5_16","year":"2018","_id":"5791","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","date_updated":"2023-09-11T12:49:55Z","external_id":{"isi":["000672802500016"],"arxiv":["1808.07608"]},"author":[{"orcid":"0000-0001-8485-1774","id":"39F3FFE4-F248-11E8-B48F-1D18A9856A87","last_name":"Fulek","first_name":"Radoslav","full_name":"Fulek, Radoslav"},{"full_name":"Tóth, Csaba D.","last_name":"Tóth","first_name":"Csaba D."}],"status":"public","month":"12","citation":{"ieee":"R.
