Finding contribution/weight of features in output from a series of data

I have a dataset which consists of the following features : a1,a2,.....aN.... sum of all the features together gives a constant output say 100. For eample the dataset may look like this. a1 a2 a3 a4 a5 a6 a7 O/p 500 100 20 700 0 0 10 100 20 25 5 700 200 300 400 100 0 800 0 0 0 0 0 100 Here the features a1, a2 etc are not identical in nature.I need to determine what values …

Find the right balance between price of a property and agent fee

Optimization problem with different type of constraints

I'm new to optimization problems. I want to find optimum values for my objective function. You can imagine my function as E = f(t1, t2, t3). I want to minimize E and following constraints limit the variables: 1- 0 < t1, t2, t3 < 255 2- t1, t2, and t3 be less as possible 3- being zero for one of this parameters is more important than overall values be low. for example (80, 150, 0) is better than (140, 50, …
