The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Can anyone run this super crazy macro for me on their supercomputer or something?

Asked by piyushdabomb in Microsoft Excel Spreadsheet Software, VB Script, Spreadsheet Software, Microsoft, Microsoft Office Suite

Tags: Microsoft Excel 2003 (Visual Basic for Applications)

Hey,

I developed an excel macro that traverses through 11 different pairing combinations (a total of approximately 135 million combinations). Given this said, its taking like 3 days to run and its been running since Monday ...(and as I type this message, its still running).

Given this said, does anyone have a supercomputer or give me advise as to how I can significantly speed up the process of this automation?

To give you an overview, here is the way this press-of-a-button works:

Essentially, lets say I have letters A, B, C, and D and for each letter I have the following (note that this can change any time to as many sub-lettered values):

A1, A2, A3, A4
B1, B2, B3, B4, B5, B6
C1, C2
D1, D2, D3, ...

What the automation does is first calculates the high level letter pairs and then the lower level pairs:
A, B, C, D to give me:

Pairs of 2:
AB, AC, AD
Now for AB, the combinations are A1,B1; A1,B2...all the way to A4,B6

Similarly, pairs of 3:
ABC, ABD, ACD
Therefore for ABC: A1,B1,C1, A1,B1,C2...all the way to A4,B6,C2

Simple enough right? Okay great...so now, low level pair, there is a comparison made and the highest value found in the "PerceivedValue" sheet for that comparison is saved.

Anyway....this is a simpliefied version. The worksheets involved are "Combinations" and "Perceived Value".

Once the whole thing runs, all the values are spit out on the "Chart" sheet. Even though there are 135 million or so combinations, only at most 65K items should be displayed on the "Chart" sheet.

-------------------------------------

Either one PLEASE try to simplify this code to give me quicker/faster results or run this on their super fast machine.

All you need to do is click "Generate Combinations" in the "Combination" worksheet.

Enclosed!
