add a +1 in the denominator to deal with the case if available resources is
zero

> 1. Describe observed behavior.
> Memory has a default capacity of 2000.0, CPU has 400.0, network has a
> distance value of either 1 or 2 (different rack); and the weights of them are
> the same (1).
> As a result, when choosing the best node for scheduling, the network plays a
> minimal role in the calculation of the geometric square of the three
> dimensions.
> 2. What is the expected behavior?
> Three resources place comparable roles in the node choosing algorithm.
> 3. Outline the steps to reproduce the problem.
> Need to assign appropriate or normalized scales to balance among the three
> dimensions.
