The unifying theme of my research is the rigorous mathematical analysis of algorithms, and computational challenges for which we are interested in designing algorithms. Until around the year 2001 the main emphasis was on computational learning theory, subsequently the emphasis has been computational game theory. Most of my work in game theory splits into 3 lines:

That third topic sits at the intersection of game theory and computational learning theory.

The Complexity of Computing a Nash Equilibrium (2006,09) is the best-known paper I have co-authored; it’s not the paper that started my interest in Algorithmic Game Theory, but it affected much of my subsequent work. This paper, showing that computation of Nash equilibrium is complete for the complexity class PPAD, raised questions about what classes of games are “hard” to solve and which are easy, also in what sense can we convince ourselves that “PPAD-complete” indicate hardness. A more general research theme is: TFNP is a class of problems that seem to be hard but are (very) unlikely to be NP-hard, so we want to understand the “complexity landscape” of this interesting region between P and NP. PPAD is just a small part of this picture…

A recent paper below that I would highlight is The Complexity of Splitting Necklaces and Bisecting Ham Sandwiches, showing that two important (and reasonably easy-to-understand) computational problems are complete for the class PPA, whose definition is similar to PPAD, but more is known about the hardness indicated by PPA-completeness. Another contribution to the above-mentioned complexity landscape of TFNP is The Hairy Ball Problem is PPAD-Complete, identifying the complexity of the computational problem associated with the classical “hairy ball theorem” and in the process, showing equivalence of the End-of-line problem (that characterises PPAD) with certain natural variants of it.

“Every morning when I wake up, I want to be surprised by whatever I might think up today!”

(Jan Sandström)

“Anyway, it goes like this: there’s this desert prison, see, with an old prisoner, resigned to his life, and a young one just arrived. The young one talks constantly of escape, and, after a few months, he makes a break. He’s gone a week, and then he’s brought back by the guards. He’s half dead, crazy with hunger and thirst. He describes how awful it was to the old prisoner. The endless stretches of sand, no oasis, no signs of life anywhere. The old prisoner listens for a while, then says, ‘Yep, I know. I tried to escape myself, twenty years ago.’ The young prisoner says, ‘You did? Why didn't you tell me, all these months I was planning my escape? Why didn't you let me know it was impossible?’ And the old prisoner shrugs, and says, ‘So who publishes negative results?’”

(from A Case of Need, by Michael Crichton)

“All day long I think of things but nothing seems to satisfy”

(from Paranoid, by Black Sabbath)

“Everyone knows by now that some triviality always has to occur in my work, but this time it goes beyond all bounds.”

(Gustav Mahler)
