If you are doing k-means or other clustering that starts from random initial conditions, then you repeat the clustering a number of times with different conditions; the clusters that appear in more of the results are more probable.
If you are trying to determine the optimal number of clusters, then you have a Problem unless you can write down exactly what it means for a clustering to be optimal in your situation; there is no generally applicable definition of "optimal" that can be used.

It is not possible for a computer program to determine whether a given output has meaning. An output is an output is an output is an output. Computers follow instructions, not assign meaning.
