| * In lecture 6 ({{:teaching:infoh417:slides-lect6.pdf|slides}}), we study the basic algorithms for physical operators, together with their cost analysis. The details (including some algorithms not discussed during the lecture) can be found in chapter 15 sections 15.1 until 15.6, pages 701-746 (in the international edition) or pages 689-734 (in the new international edition). The interested reader is also advised to read Section 15.7 (although this will not be interrogated during the exam). | * In lecture 6 ({{:teaching:infoh417:slides-lect6.pdf|slides}}), we study the basic algorithms for physical operators, together with their cost analysis.
