Excellent Master Theses 

Emilia Dunfelt

From Non-Local Games to Embeddings of Groups: Resolving Tsirelson’s Problem
Advisor: Sven Raum

Emilia Dunfelt is awarded the SMC prize for her excellent master thesis. In her thesis, she gives an accessible exposition of Slofstra's 2016 solution of the strong Tsirelson's problem, a notable and deep recent result in quantum information theory, based primarily on group-theoretic tools. The thesis draws together a broad range of material to give a more thorough, self-contained, and elementary account of Slofstra's result than was previously available in the literature.

Johan Hallberg Szabadváry

Single- and Multi-Fidelity Bandits in Monte Carlo Tree Search: from the Casino to Mobile Network Optimization
Advisor: Maxime Bouton (Ericsson), Alessandro Previti (Ericsson) and Yishao Zhou

Johan Hallberg Szabadváry is awarded the SMC prize for his excellent master thesis. He proposes a new algorithm to solve a network optimization problem of the telecommunications company Ericsson. He independently applies mathematical techniques from advanced analysis, probability theory, and the theory of optimization, to attack Ericsson's concrete problem of large-scale discrete optimization of several parameters describing their base stations. Hallberg's thesis contains extensive simulations along with well-formulated descriptions of mathematical aspects and his novel algorithm.

Nicole Hedblom

Random Edge is not faster than Random Facet on Linear Programs
Advisors: Per Austrin

Nicole Hedblom is awarded the SMC prize for her excellent master thesis. She provides new results for the widely used Simplex method for Linear Programming. Namely, Nicole proves a new lower bound on the expected number of steps of the Simplex method in the case when the Random Edge pivoting rule is used, in which a uniformly random improving edge is chosen at each step. Nicole’s result is an improvement of a previous result by Friedman et al.

Carolina Fransson

Stochastic epidemics on random networks and competition in growth
Advisor: Pieter Trapman and Daniel Ahlberg

Carolina Fransson is awarded the SMC prize for her excellent doctoral dissertation, with her ingenious and innovative contributions to the theory of stochastic epidemics on random networks that include clustering and degree dependent contact rates, competition in growth, as well as a well-written introduction to the area of stochastic epidemics.
