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! |

Asked by choelt in Algorithms
I have a process where we are manually trying to sort containers of varying weights into 4 bins of nearest equal total weights. Here is a sample of typical data with 13 items:
1.68
1.76
2.34
3.88
4.04
5.12
6.10
7.00
7.02
7.24
7.68
8.20
8.62
Now I need to determine which items to group into bins. I need 4 bins with the closest matching total weights possible. So in this case the total weight is 70.68. So I need 4 bins containing as close to 17.67/ea. possible. There will always be 4 bins no matter how many items. The total items varies usually between as few as 6 to upwards of 40. Also let me point out that it doesn't matter how many items are in each bin. One bin could have 5 items while another has only 2. We're just trying to match total weights as close as possible.
I'm a VB developer, but can understand most all basic logic as long as it is in somewhat readable form. (why/how explanations help me considerably) I have been working on some basic sorting using arrays, but I'm not able to come up with anything that consistently calculates a best case scenario for different data sets. I need help with an algorithm that will work much more consistently than the manual system we are using now which is for the most part trial and error.
