====== Integer Programming and Computational Social Choice 23/24 ======


This is essentially another iteration of the [[:teaching:stfa2223|Selected Topics from Algorithms]] course, and this link contains potentially useful resources.

| 26. 2. | Fixed dimension IPs, intro to iterative augmentation. **[LN up to Lemma 7]** |
| 4. 3. | More details for iterative augmentation. **[LN up to Lemma 16]**|
| 11. 3. | Norm bound, DP for case of small $m$ and $\|A\|_\infty$ **[LN Lemma 16, 17]**; treedepth, block-structured matrices **[LN 3.4]**; norm bound for $n$-fold IPs **[LN Lemma 29]**|
| 18. 3. | norm bounds and augmentation IP algorithms for $n$-fold and $2$-stage stochastic IPs [LN 3.5.1 and 3.6]|
| 25. 3. | Extensions: proximity theorems, coefficient reduction, strongly-poly algorithms, sensitivity [LN 4 + 5]| 
| 1. 4. | //Easter Monday//|
| 8. 4. | Intro to voting: election, voting rule, some examples **[LN 6.1-6.3]**; <typo fv:small-caps>YoungScore</typo> and <typo fv:small-caps>DodgsonScore</typo> as fixed-dimension ILPs (double-exponential algorithm), and as few rows / $n$-fold ILPs (single-exponential algorithm). <typo fv:small-caps>DodgsonScore</typo> is the same thing as unit cost Condorcet-<typo fv:small-caps>Swap Bribery</typo>. Similar formulations are in **[LN 8.1]**. |
| 15. 4. | //Cancelled - KAM/IUUK spring school//|
| 22. 4. | Bribery and manipulation actions as moves in societies, various voting rules, FPT algorithms.|
| 29. 4. | More voting rules; what's the deal with Young-<typo fv:small-caps>Swap Bribery</typo>; define <typo fv:small-caps>Campaigning Game</typo>, connect it to Presburger Arithmetic.|
| 6. 5. | Cooper's algorithm for Presburger Arithmetic [[http://www2.imm.dtu.dk/courses/02917/Presburger1.pdf|slides]], discuss applications.|
| 13. 5. | //Plan: Opinion diffusion//|
