This program will bring together researchers from both the discrete and continuous optimization communities in order to stimulate further interaction at this interface.

### Spring 2017

Jan. 10 – May 12, 2017

This program aims to extend the reach and impact of CS theory within machine learning, by formalizing basic questions in developing areas of practice, advancing the algorithmic frontier of machine learning, and putting widely-used heuristics on a firm theoretical foundation.

Jan. 10 – May 12, 2017

This program will gather researchers in theoretical computer science, combinatorics and number theory to develop a unified approach to notions of pseudorandomness and their applications.

### Fall 2016

Aug. 17 – Dec. 16, 2016

Classical approaches to algorithm design are both over-pessimistic (in making worst-case assumptions about the input) and over-optimistic (in assuming that the input is completely specified). This program explores alternatives to worst-case analysis of algorithms, as well as new methods for addressing uncertainty in instance specifications, with reference to a broad range of applications in learning, optimization and control.

Aug. 17 – Dec. 16, 2016

Logic in computer science has long been associated with two main themes: the interaction of logic with algorithms and complexity theory, and the semantics of programs and processes. This program will bring together researchers from both ends of this spectrum, with the aim of bridging this decades-old divide.

### Spring 2016

Jan. 11 – May 13, 2016

This program aims to unify data-driven and theoretical developments in bioinformatics by bringing together leaders and young scientists with strong interests in the algorithmic, methodological and theoretical aspects of computational biology.

Jan. 11 – May 13, 2016

Research on computational aspects of counting problems and partition functions has recently seen significant advances. This program aims to better understand the computational complexity of both exact and approximate counting problems, and their relationship to phase transitions in combinatorics and statistical physics.

### Fall 2015

Aug. 19 – Dec. 18, 2015

Economics and computer science have developed a remarkable number of points of contact over the past two decades. This program aims to build on these existing interactions in order to identify and make progress on a new generation of research problems at the intersection of the two fields.

Aug. 19 – Dec. 18, 2015

This program will explore deep connections between algorithm design and lower bounds in computational complexity, with the goal of understanding the exact amount of time needed to solve a variety of basic computational problems.

### Summer 2015

May 18 – Aug. 14, 2015

As organizations and individuals are increasingly outsourcing storage and computation to large third-party systems, the need to simultaneously guarantee privacy, availability of data and correctness of computations is more crucial than ever. This program focuses on new developments in cryptography that address these issues, including homomorphic encryption, program obfuscation and verifiable outsourcing.

### Spring 2015

Jan. 13 – May 15, 2015

The program will bring together experts in information theory and theoretical CS to explore the application of information theoretic techniques in complexity theory and combinatorics, the theory and applications of coding theory, and connections between information theory, machine learning and big data.

### Fall 2014

Aug. 21 – Dec. 19, 2014

This program addresses the use of spectral methods in confronting a number of fundamental open problems in the theory of computing, while at the same time exploring applications of newly developed spectral techniques to a diverse array of areas.

Aug. 21 – Dec. 19, 2014
