Lecture Recordings and Material

Date	Topic	Recording	Slides	Reading Material
19.04.2023	Introduction, Two Generals			Introduction: Chapter 1 and Chapter 2 of [Aspnes] Two Generals: Chapter 8 of [Aspnes]
24.04.2023	Broadcast, Convergecast, Spanning Trees			Chapter 2 of [Wattenhofer] Chapter 3 and Chapter 4 of [Aspnes]
08.05.2023	Leader Election in Rings			Chapter 3 of [Wattenhofer] Chapter 5 of [Aspnes]
15.05.2023	Causality in Distributed Systems			Chapter 6 of [Aspnes]
22.05.2023	Consensus I			Chapter 11 and Chapter 18 of [Aspnes]
	Chapter 11 of [Aspnes] proves the impossibility of asynchronous consensus for message-passing systems, while in the lecture, we did the same proof for shared memory systems. Chapter 18 of [Aspnes] contains much more details about the consensus hierarchy than discussed in the lecture.
05.06.2023	Consensus II			Chapter 9 and Chapter 10 of [Aspnes]
	Chapters 9 (on synchronous consensus) and 10 (on Byzantine agreement) of [Aspnes] contain more details than what we discussed in the lecture.
12.06.2023	Coloring and MIS			The coloring algorithm for rooted trees also appears in Chapter 1 of [Wattenhofer]
	The lecture was prepared and recorded by Alkida Balliu. In the lecture on 12.06., we will summarize and discuss the content of the video and possibly some small additional topics that are directly related to the content of the video lecture.
19.06.2023	Randomized Coloring & MIS			The randomized MIS algorithm also appears in Chapter 7 of [Wattenhofer]
	The lecture was prepared and recorded by Dennis Olivetti. In the lecture on 19.06., we will summarize and discuss the content of the video and possibly some small additional topics that are directly related to the content of the video lecture.
26.06.2023	Locality Lower Bounds			Linial's original version of the lower bound for 3-coloring rings is described in Chapter 8 of [Wattenhofer]. The simpler proof that was discussed in the lecture appeared in [Laurinharju,Suomela].
	The lecture was prepared by Dennis Olivetti. For a version of the lecture that was prerecorded by Dennis Olivetti, see the video below.

10.07.2023	Synchronization			Chapter 11 of [Wattenhofer].
17.07.2023	Massively Parallel Computations			Further details and a more advanced coverage of the topic can for example be found in Chapter 3 of [Ghaffari: Massively Parallel Algorithms].
