The rectilinear Steiner tree problem (RSTP) is a classical problem having numerous real-world applications, including VLSI routing. Since the RSTP is NP-hard, developing polynomial heuristics which can produce near optimal solutions has been the primary approach to solve the RSTP. Many of these algorithms (e.g., 1-Steiner) use Hanan points. However,(More)
Use of vasoconstrictors in local anaesthesia is well known. The study was done on 30 patients who underwent removal of bilateral impacted third molars. The aim of the study was to compare the efficacy of lignocaine with clonidine and lignocaine with adrenaline in respect to onset, duration of anaesthesia, and postoperative analgesia along with hemodynamic(More)
