Our results show that certain types of additional input information cannot possibly permit faster solutions for these problems. The main idea in all our lower bound proofs is the use of the index of a point as an additional coordinate.1272860 bytes425738 bytesapplication/pdfapplication/postscripten-UScomputer sciencetechnical reporttechnical report
