] | It seems the objective is a quadratic function and all the constraints are linear. So I think you can solve it by standard quadratic programming solvers.
If we write `S_i` be the half-size of i-th box, and the Pi's are given, then:
```
Minimize y
with respect to C_1, C_2, ...C_n
subject to
y = sum_i (P_i - C_i)^2
C... | Just for completion, I found a (probably subtompimal) solution that works pretty well and is very easy to implement.
1. Place all boxes with their Ci's at their Pi's.
2. Go over all boxes, from left to right and do the following:
1. Check if box i overlaps with the box to its left. If it is the first box, check if it... |

] | Since you said that you have tried with ActionLink and it did not work, here is how it would work.. instead of passing the type that you are looking for as a parameter for the Display action, pass the `ID` of the record.
So it would look something like this:

1) You do not render any `<input>` elements in which you send the selected values back to the controller. Use `Html.HiddenFor` or `Html.EditorFor` in addition to `Html.DisplayFor`.
2) In order for the MVC Modelbinder to be able to bind your list, use a `for` loop instead of `for... |
