There are three decisions that are used in deciding the numbers used in my lottery site
1. What numbers are rarely chosen
-An analysis of past winning results as described in this paper
-A simpler method is described in "maximum entropy parallel computation and lotteries"
2. What types of patterns are rarely chosen
A number of patterns are known to be avoided
-Picking numbers with the same distance between them. For example picking numbers that are always separated by 6 numbers
-Trying To Be Random in Selecting Numbers for Lotto
-The statistics of smallest space in lottery tickets
4. What specific patterns are rarely chosen
-Hot hand and gamblers fallacy
-Does the behaviour of lottery players consist Gamblers Fallacy? Evidence from Taiwan Market. I cannot find a link for this paper currently
-There are some numbers that are known to be chosen commonly. Previously winning numbers, certain patterns with low Kolmogorov complexity.
By combining knowledge from the research listed I have produced a lottery betting program that improves your average return
