A python binding is available for some C++ objects provided permitting to easily solve an optimization problem by regression. Different methods are available : - Dynamic programming methods based on Monte Carlo with regressions (global, local and sparse regressors), for underlying states following some uncontrolled Stochastic Differential Equations (python binding provided). - Semi-Lagrangian methods for Hamilton Jacobi Bellman general equations for underlying states following some controlled Stochastic Differential Equations (C++ only) - Stochastic Dual Dynamic Programming methods to deal with stochastic stocks management problems in high dimension (C++ only) For each method, a framework is provided to optimize the problem and then simulate it out of the sample using the optimal commands previously calculated. Parallelization methods based on OpenMP and MPI are provided in this framework permitting to solve high dimensional problems on clusters. ------------------------------------------------------- From: Iain Duff [log in to unmask] Date: August 23, 2016 Subject: Linear Algebra and Parallel Computing, UK, Sep 2016 Franco-Scottish Seminar 2016: Linear Algebra and Parallel Computing at the Heart of Scientific Computing. 21 September 2016. The Royal Society of Edinburgh (RSE) and the French Embassy in London are collaborating in a programme of science events designed to explore and publicly present areas of science where both Scotland and France have a powerful presence. These events are intended to stimulate Franco-Scottish collaboration in science, present new scientific ideas and their social and commercial implications to the public and increase awareness of French and Scottish science in each other's country. This year, the seminar, to be held at the Royal Society of Edinburgh, will focus on the topic of "Linear Algebra and Parallel Computing at the heart of Scientific Computing". Most numerical computations and simulations have at their core the solution of systems of linear equations. As the computations increase in scale and the simulations become more detailed, the size of such system increases. This seminar is focused on recent research into improving the solution of such large systems and some novel applications which can now be addressed. Much of this research has involved direct collaboration between Scotland and France. The one-day seminar will be held on the 21st September at the RSE headquarters at 22-26 George Street in Edinburgh. The programme will begin at 9.00 and finish at 17.30. Further information and a full programme is available on the RSE website: https://www.royalsoced.org.uk/events/event.php?id=460 and applications to attend should be sent to Rita Velaviciute, [log in to unmask] or tel: 0131 240 2782. ------------------------------------------------------- From: Anja Milde [log in to unmask] Date: August 24, 2016 Subject: Reduced-Order Modeling for Simulation and Optimization, Germany, Nov 2016 KoMSO Challenge Workshop on Reduced-Order Modeling for Simulation and Optimization: Powerful Algorithms as Key Enablers for Scientific Computing taking place on November 17 & 18, 2016 at Bosch Research Campus, Renningen, Germany. http://www.KoMSO.org <http://www.komso.org/> Growing demand for numerical solutions in scientific computing (modeling, simulation, data analysis, optimization problems in many application fields) requires ever higher algorithmic and computational performance. It has been shown in many cases that the advancement of mathematical algorithms has increased the arithmetic performance clearly more than the improvements of computer hardware alone. The KoMSO workshop puts particular emphasis on the advancement of efficient numerical procedures. Presentations of new out-of-the-box algorithmic solutions for scientific computing are invited - in particular for reduced-order MSO. It is the purpose of this workshop to bring together the creators and developers of new, optimal fast mathematical algorithms and their potential industrial users. Requirements, application fields, needs, and benefits of effort-saving fast algorithms will be presented. We invite you to submit contributions for oral presentations. We call for abstracts of maximum 2 pages. Submissions should be written in English.

The three year post is funded through a Cancer Research UK Multidisciplinary award in collaboration with Professor Robert Insall at the Beatson Institute for Cancer Research in Glasgow. Metastasis is the dominant cause of cancer mortality, but it is poorly understood. One issue is the great complexity of cellular behaviour. Fundamental advances need both better theoretical understanding of the dynamics of cell migration, and more data to disentangle it. The project has three research areas, each involving both theoretical and practical components, but at different scales. These are: a better understanding of the mechanisms that make individual cells migrate, identifying self- generated chemotactic gradients in metastasis and interactions between chemotactic gradients, migrating cells and their environments. Candidates are expected to have a PhD in applied mathematics, scientific computing, numerical analysis, physics, engineering or a cognate discipline. Experience of implementing finite element methods for the solution of partial differential equations is essential. Experience of the development of mathematical models in the life sciences is desirable although not essential.
