Project – Algorithm Optimization (Proof of Concept for a larger dataset and ongoing project across multiple markets) Skills - Mathematics, query optimization, statistics & distribution, database programming, software development, Algorithms Delivery - ASAP One data set of approximately 15k records (market updates) is provided. This is provided in the attached sheet “Market Records”. Each record within this caries 16 variables including a score for each record. Through a combination of mathematics, query optimization, statistics & distribution, database programming, software development etc, I am looking for a freelancer to deliver the optimal query that will generate the highest score form the records. PLEASE NOTE - Time is NOT of the essence, the database is not part of the infrastructure, the optimal query is defined by the final score generated by the query. You must have the capability (or be able to develop a solution) to systematically run through the dataset automatically adjusting the variables and parsing the records to determine the highest score and therefore the optimum query. The query will use simple true/false logic driven out of each variable. The score is calculated by simply adding the all the scores for the records selected by the final query The records can be queried using any of the variables in the file (columns B-W) see attached excel, however there are some simple rules: 1. A minimum of score of 5 must be achieved. No queries scoring below 5 can be submitted 2. The only syntax’s available to be applied to the variables are greater than equal to, or less. The query cannot set min and max values. 3. Where two variables have the same number but two versions (See column headings) only one of these can be active in the query. They cannot both be enabled 4. You don’t have to enable/utilize all variables 5. No two records within 40seconds of each other (each record has timestamp) can be counted. The first record (in chronological order) is always the record that is scored. If a further record is included within 40seconds its score must be ignored. More than one query can be developed if required (Up to 6 queries permitted) and applied to data-set. The score for each query will contribute to the total, however rule 2 still applies, even across separate queries. Depending on bids for the project this project may be reposted to source more than one response, all accepted bids will be awarded on completion. The successful developer should be able to perform the same evaluation for a data-set of up to 200k records and be readily available for hire.

Hello Sr, I'm a qualified Data Scientist with vast experience in optimization problems from professional work and various competition platforms (Top Coder and Kaggle). I have downloaded the [login to view URL] file and understand your request. My proposed solution is to run a Decision Tree algorithm through the open source statistical software R to get the best cuts for the data set (and its variables) and then develop the corresponding query with the mentioned cuts, ofcourse I will have to manipulate the objective function to search for higher values. Finally I would like to notify my working hours are of (UTC -4) and I'm available from 9:00 to 23:00 through skype, hangout, gtalk, etc. Thanks for the opportunity, Hope to work with you,

Hi, I am interested in the project, it looks challenging. However I am puzzled by that requirement of the score being above 5, while there is no entry in the score column above 5. Let me know if you are interested in my profile, I will spend more time in this project. Regards.

Hi, I am working as Lead Pricing Analyst in a Fortune 500 MNC. I have worked on pricing models, income statements, value-pricing projects etc. Some of the projects which I have done include: 1) Time series analysis to determine relationship and prediction of retail petrol vs from wholsale petrol prices 2) Multi-regression for product harvesting strategy using dummy variables wherever applicable. Used Minitab and JMP for above projects. I have worked extensively on excel and VBA in my job and here on freelancer as well. I believe I can help in your work. Please have a look at reviews provided by previous employers. Please contact for further discussion. Regards! Vikas

Hi, By way of introduction, I am Adarsh Dattatri and I work as a Data Scientist. After going through your project files, I would like to express my interest to work on the optimization algorithm. I can ensure a quick turnaround because I work with a couple of other Data Scientists and machine Learning professionals. Please let me know your interest. The algorithm will be implemented in Python.

I assume the data will be in Excel, always. I assume I am allowed to use VBA as part of any solution. I assume you would like this algorithmic solution to run quickly (how quickly? is 1 minute too long? 1 hour?...) I assume the minimum score of 5 refers to any single record. This either implies that no "query" is acceptable if any of the data records in this data set scores less by this query or that you just drop the <5 records and sum up only the >5 records for the final TOTAL score for the data set.. or something entirely different...? I do not understand the meaning of the term "variables" in your "...automatically adjusting the variables..." since the variables are defined earlier as the 16 fields in the data row (in a record). I do not understand what "...simple true/false logic driven out of each variable" means either, beyond the uncertainty with the term "variable" explained above. Also, the "multiple query" bit is not quite clear to me either, unfortunately. I am sure these and other "issues" we can resolve easily and quickly. I hope my pointing out the uncertainties in the Project Description clearly show to you that I know what I am doing here. After all said and done, I've been successful with working out similar projects before, for others and for myself, so I have no doubt about the positive end result. Gene
