Hi, I need a custom encryption/decryption algorithm which should be based on a 4 byte key (DWORD). The algorithm must be complicated enough to deter reverse engineering or at least make it hard. It should work in c++ and php i.e. encrypted data from a c++ program should be decrypt-able by php code. These are the c++ function prototypes (php ones are similar): void encrypt(vector<char>& buffer, DWORD key) void decrypt(vector<char>& buffer, DWORD key) Your submission must include a wide range of test cases to make sure the algorithm doesn't break.The algorithm has to be private, no open-source or publicly available algorithms will be accepted! Please include some details about the algorithm you intend to implement, pref. pseudo code. Thanks.

I need a simple web interface for input/output of time series data that is then fit to a dependent variable series via multiple linear regression (MLR) in R using various model selection algorithms (forward, backward, sequential, etc.). The data will consist of a time series of roughly 20 periods (this can vary from ~12 to ~40) and anywhere from ~80 to ~1,000 independent variables. MLR models will be limited to 15 regressors + intercept. For each set of regressors I would want the top ten models (i.e. top ten models for 15 regressors + intercept, top ten models for 14 regressors + intercept, top ten models for 13 regressors + intercept, etc.). Additionally, certain regressors may be identified as "necessary" beforehand and must then be present in all models. Descriptive statistics will include R2; adjusted R2; standard error; AIC; and BIC. Time Series Partitioning: for each set of data, the entire process needs to be run on several in-sample/out-of-sample partitions. For exa...

I am trying to create a table where I am going to enter items. Each item would be classified based on different aspects, i.e. in the same row of the item there would be cells for the different types of classifications (see attachment 1). Each classification is a hefty list (some with 6000 items) with tree level structure (see attachment 2). The job would be to create a dropdown list in a single cell (so the approach to create dependent dropdown list using as many cells as many levels the classification has is not acceptable) to select a classification title and since there are around 6000 titles to be feasible I would like to shape this drop down list as a menu, so that at first click I would be able to choose from the Level 1 titles then if there are Level 2 titles available I could choose from those and once the Level 2 is chosen I could choose from Level 3 titles and so on, basically like the start menu in the old Windows (see attachment 3).
