This is the first time GECCO has been held in Philly. We very much hope you enjoy this historic American city and all it has to offer. This will be my 14th year attending GECCO. I have contributed a number of papers and have enjoyed many thought-provoking presentations over the years. GECCO has played a very important role in my research program and in the training of many of my students and postdocs. I agreed to serve as General Chair of GECCO-2012 because it was time to give back to the community I have enjoyed being a part of since 1999. Terence Soule served as the editor-in-chief this year and did a very skillful job maintaining the high quality of the conference. GECCO-2012 accepted 172 full papers for oral presentation out of a total of 467 submitted. This is an acceptance rate of less than 37%. I am very thankful to Terry, Anne Auger, our Proceedings Chair, and all the track chairs for their hard work managing the review, selection and scheduling process for the scientific papers. Thanks to Mark Montague from Linklings and Lisa Tolles from Sheridan Printing for their assistance with the publication of the proceedings. One of the highlights of every GECCO is the free tutorials and the free workshops held during the first two days of the conference. I found these to be incredibly helpful when I was still learning about the field. Thanks to Gabriela Ochoa for chairing the tutorials and Bill Rand for chairing the workshops. In addition to the main program, there are many other parts that make GECCO a special and meaningful experience. Marylyn Ritchie served as Local Chair and was very helpful with planning our visit to Philly. Xavier Llorà did a superb job of publicity with the help of our webmaster and design consultant, Gerardo Valencia. Daniele Loiacono did a great job as Competitions Chair and, as Student Chair, Josh Bongard masterfully oversaw the process of awarding student travel grants. I would also like to thank Thomas Bartz- Beielstein, David Davis and Joern Mehnen for their role as Evolutionary Computation in Practice Chairs. I couldn’t have planned GECCO-2012 without the generous time commitment of all the chairs mentioned above. I would also like to thank Wolfgang Banzhaf and Marc Schoenauer from the ACM SIGEVO Business Committee and Franz Rothlauf, the ACM SIGEVO Treasurer, for their encouragement and assistance navigating the enormous number of details from budgets to planning and execution. Additionally, I would like to thank Roxane Rose and Jill Skuba from Executive Events for their expert handing of the many logistical and registration-related details that are needed to make the conference a success. Finally, I would like to thank you, the authors, presenters, reviewers, and all the other attendees. It is your participation that makes GECCO what it is, one of the premier conferences on evolutionary computation and a source of great discussions, ideas, and inspirations. Thank you all for your involvement. Jason H.

  • Krawtchouk Matrices from Classical and Quantum Random Walks
    Krawtchouk matrices from classical and quantum random walks Philip Feinsilver and Jerzy Kocik Abstract. Krawtchouk’s polynomials occur classically as orthogonal polyno- mials with respect to the binomial distribution. They may be also expressed in the form of matrices, that emerge as arrays of the values that the polynomials take. The algebraic properties of these matrices provide a very interesting and accessible example in the approach to probability theory known as quantum probability. First it is noted how the Krawtchouk matrices are connected to the classical symmetric Bernoulli random walk. And we show how to derive Krawtchouk matrices in the quantum probability context via tensor powers of the elementary Hadamard matrix. Then connections with the classical situa- tion are shown by calculating expectation values in the quantum case. 1. Introduction Some very basic algebraic rules can be expressed using matrices. Take, for example, (a + b)2 = a2 + 2ab + b2 1 1 1 (2) (a + b)(a − b) = a2 − b2 ⇒ Φ = 2 0 −2 (a − b)2 = a2 − 2ab + b2 1 −1 1 (the expansion coefficients make up the columns of the matrix). In general, we make the definition: Definition 1.1. The N th-order Krawtchouk matrix Φ(N) is an (N +1)×(N +1) matrix, the entries of which are determined by the expansion: N N−j j X i (N) (1.1) (1 + v) (1 − v) = v Φij . i=0 The left-hand-side G(v) = (1 + v)N−j (1 − v)j is thus the generating function for the row entries of the jth column of Φ(N).

Stacey Staples∗ Abstract Kravchuk polynomials arise as orthogonal polynomials with respect to the binomial distribution and have numerous applications in harmonic analysis, statistics, coding theory, and quantum probability. The relation- ship between Kravchuk polynomials and Clifford algebras is multifaceted. In this paper, Kravchuk polynomials are discovered as traces of conjuga- tion operators in Clifford algebras, and appear in Clifford Berezin integrals of Clifford polynomials. Regarding Kravchuk matrices as linear operators on a vector space V , the action induced on the Clifford algebra over V is equivalent to blade conjugation, i.e., reflections across sets of orthogonal hyperplanes.

We call Krawtchouk-Griffiths systems, or KG-systems, systems of multivariate polynomials orthogonal with respect to corresponding multi- nomial distributions. The original Krawtchouk polynomials are orthogonal with respect to a binomial distribution. Our approach is to work directly with matrices comprising the values of the polynomials at points of a discrete grid based on the possible counting values of the underlying multinomial distribu- tion. The starting point for the construction of a KG-system is a generating matrix satisfying the K-condition, orthogonality with respect to the basic probability distribution associated to an individual step of the multinomial process. The variables of the polynomials corresponding to matrices may be interpreted as quantum observables in the real case, or quantum variables in the complex case. The structure of the recurrence relations for the orthog- onal polynomials is presented with multiplication operators as the matrices corresponding to the quantum variables. An interesting feature is that the associated random walks correspond to the Lie algebra of the representation of symmetric tensor powers of matrices.

  • Krawtchouk Polynomials and Krawtchouk Matrices
    Krawtchouk polynomials and Krawtchouk matrices Philip Feinsilver and Jerzy Kocik Department of Mathematics Southern Illinois University Carbondale, IL 62901 Abstract Krawtchouk matrices have as entries values of the Krawtchouk poly- nomials for nonnegative integer arguments. We show how they arise as condensed Sylvester-Hadamard matrices via a binary shuffling function. The underlying symmetric tensor algebra is then presented. To advertise the breadth and depth of the field of Krawtchouk poly- nomials/matrices through connections with various parts of mathematics, some topics that are being developed into a Krawtchouk Encyclopedia are listed in the concluding section. Interested folks are encouraged to visit the website http://chanoir.math.siu.edu/Kravchuk/index.html which is currently in a state of development. 1 What are Krawtchouk matrices Of Sylvester-Hadamard matrices and Krawtchouk matrices, the latter are less familiar, hence we start with them. Definition 1.1 The N th-order Krawtchouk matrix K(N) is an (N +1)×(N +1) matrix, the entries of which are determined by the expansion: N N−j j X i (N) (1 + v) (1 − v) = v Kij (1.1) i=0 Thus, the polynomial G(v) = (1 + v)N−j (1 − v)j is the generating function for the row entries of the jth column of K(N). Expanding gives the explicit values of the matrix entries: (N) X j N − j K = (−1)k . ij k i − k k where matrix indices run from 0 to N. 1 Here are the Krawtchouk matrices of order zero, one, and two: 1 1 1 1 1 K(0) = 1 K(1) = K(2) = 2 0 −2 1 −1 1 −1 1 The reader is invited to see more examples in Table 1 of the Appendix.

  • Krawtchouk Polynomials and Krawtchouk Matrices
    Krawtchouk polynomials and Krawtchouk matrices Philip Feinsilver and Jerzy Kocik Department of Mathematics Southern Illinois University Carbondale, IL 62901 Abstract Krawtchouk matrices have as entries values of the Krawtchouk polynomials for nonnegative integer arguments. We show how they arise as condensed Sylvester-Hadamard matrices via a binary shuffling function. The underlying symmetric tensor algebra is then presented. To advertise the breadth and depth of the field of Krawtchouk polynomials/matrices through connections with various parts of math- ematics, some topics that are being developed into a Krawtchouk En- cyclopedia are listed in the concluding section. Interested folks are encouraged to visit the website http://chanoir.math.siu.edu/wiki/KravchukEncyclopedia which is currently in a state of development. arXiv:quant-ph/0702073v1 7 Feb 2007 1 What are Krawtchouk matrices Of Sylvester-Hadamard matrices and Krawtchouk matrices, the latter are less familiar, hence we start with them. Definition 1.1 The N th-order Krawtchouk matrix K(N) is an (N + 1) × (N + 1) matrix, the entries of which are determined by the expansion: N N−j j i (N) (1 + v) (1 − v) = v Kij (1.1) Xi=0 1 Thus, the polynomial G(v)=(1+ v)N−j (1 − v)j is the generating function for the row entries of the jth column of K(N). Expanding gives the explicit values of the matrix entries: j N − j K(N) = (−1)k . ij k i − k Xk where matrix indices run from 0 to N. Here are the Krawtchouk matrices of order zero, one, and two: 1 1 1 1 1 K(0) = 1 K(1) = K(2) = 2 0 −2 1 −1 1 −1 1 The reader is invited to see more examples in Table 1 of the Appendix.
