doktorandsky seminar last Thursday
by Robert Samal 07 Nov '21

07 Nov '21

Dear all, I've been informed that one participant of the last seminar did test positively on covid (antigen test today). So I am letting you know. The person was vaccinated as I suppose are most of you, so there should be very little danger, and according to the official regulations this would not count as a risky contact anyway (> 2 m distance), see https://covid.gov.cz/en/situations/infection-and-general-measures/i-was-ide… However, if you want to be extra careful, perhaps before visiting a vulnerable relative, I understand the best time to try a PCR test is 5-7 days after a contact. Stay safe, R -- Robert Šámal IÚUK MFF UK -- CSI of Charles University

graduate students' reading seminar (Tung Anh Vu -- IP via Steinitz Lemma)
by Robert Samal 21 Oct '21

21 Oct '21

Dear all, This Thursday we will have another talk at the seminar. Tung Anh Vu will speak about a paper by Eisenbrand and Weismantel about Proximity Results and Faster Algorithms for Integer Programming Using the Steinitz Lemma (SODA 2018, ACM Transactions on Algorithms 2019) It is about a fast algo for IP (although still exponential) that is based on an innocuous lemma about vectors. Tung insists you don't need any special prerequisites to understand the talk. Same place&time as last week: Time: Thursday 9:50-12:10 Place: S9 For people who cannot come, zoom: https://cesnet.zoom.us/j/95284272991?pwd=aGxTM29NZVZGUjJWcG8vYWRmYXRSQT09 (I hope I will be able to resolve the sound issues.) See you there, R PS For this email I have used the email conference dedicated to the seminar -- plus a few additions in the Cc. I hope I did not miss anyone. And also I ask the people in the Cc to kindly subscribe to the list at https://kam.mff.cuni.cz/mailman/listinfo/dokt-seminar-l Thanks. -- Robert Šámal IÚUK MFF UK -- CSI of Charles University
