Oritatami is a computational model of this phenomenon, which lets its transcript, a sequence of beads (abstract molecules) fold cotranscriptionally via interactions between beads according to its ruleset. In this paper, we study the problem of removing self-attractions, which lets a bead interact with another bead of the same kind, from a given oritatami system without changing its behavior. We provide an algorithm for that with overhead linear in the delay parameter, which should be considerably smaller than the length of its transcript. We also show that this overhead is tight. %G English %Z TC 1 %Z WG 1.2 %2 https://inria.hal.science/hal-01657016/document %2 https://inria.hal.science/hal-01657016/file/440206_1_En_13_Chapter.pdf %L hal-01657016 %U https://inria.hal.science/hal-01657016 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC1 %~ IFIP-WG %~ IFIP-DCFS %~ IFIP-WG1-2 %~ IFIP-LNCS-10316
