Hi, I need someone who could implement the following algorithm in graphX/Pregel. http://www.wisdom.weizmann.ac.il/~harel/papers/highdimensionalGD.pdf I already have some bits of code attached that can be used as a string point for the first part of the calculation.

I have an algorithm to generate counterfactuals in dynamic programming problem that is currently written in Stata but needs to be written in MATLAB or AMPL for more efficient optimization. ... What I need the freelancer to do: - Understand the algorithm, written in English, and the code, written in Stata - Efficiently and clearly write a code in MATLAB or AMPL that does the same thing (minus any optimization, which currently isn't part of the Stata code) - As a bonus, it would be nice to incorporate optimization in the MATLAB or AMPL code, using MPEC or some other gradient-based method like fminunc Key skills needed for the job: - Understanding mathematical concepts, such as expectations - Efficient coding, both in terms of computation, memory, and time; for example, the problem may involve sparse matrices - As a bonus, understanding methods of optimization, and specifying numerical or analytical gradients and Hessian matrices A successful engagement will look like the following: - The Stata code will be replicated (i.e., results that the Stata code produces will also be produced by the MATLAB or AMPL code) - Potentially inefficiencies or even mistakes in the Stata code could be identified - The foundation for something that could be used in an optimization routine will be constructed, potentially the optimization itself could be done under this contract A successful engagement will likely lead to future jobs

Here's your challenge. Please complete in one week or less and return to me. Imagine that you run an ice cream shop. You sell three different main items – ice cream cones, milkshakes, and floats. You have a large number of different flavors of ice cream available. Ice cream cones can be made of either one or two scoops, and each scoop can be any available flavor. The cone can be only one of the available waffle cones. Milkshakes can only be made with one flavor of ice cream, and must be made with either skim, whole, or 2% milk. Floats can be made with any number of scoops of any number of different flavors, plus one available soda. Finally, your store offers discounts, but only on milkshakes and floats and not on ice cream cones. Utilizing Object Oriented Programming, design and build a system that will store the listed information. Your submitted solution should contain not only the source code for the classes you have created, but also contain example usage of these classes. Please do not utilize pre-built frameworks. You must: - create at least one of each of your product types (ice cream cone, milkshake, float) - purchase at least one item with a discount - use at least 5 different flavors of ice cream - use at least two different serving vessels(waffle cone, cup, etc). - use at least 3 different flavors of soda Here are some answers to questions you may ask: I assume that PHP is the preferred language for this OOP project? Yes, PHP is preferred but any language can be used. Please no frameworks. Should the storage of information be performed in a MySQL or other database, or do you mean that the information should just be stored in the objects I create for this project? The objects can store the information, although you could use a mysql database. Should the solution be completed with an HTML web form for ordering? It is not required, but can be used if you prefer. When submitting examples of usage, do you also mean screenshots or simply applications I write which utilize the objects I create? We would like to see the applications, not screenshots. Do you also need to see class diagrams or other UML type diagrams? Not unless you prefer to send those. Should this project turn out well, you'll be hired for a larger project in a full-time capacity. Thanks and good luck!
