🎯 Algorithm-Based Semi-Auto Lotto Combiner

Key numbers plus algorithmic combinations

Choose 1 to 4 key numbers and a heuristic algorithm fills in the rest to create balanced combinations. You can pick from 4 algorithms: Balanced, Random, Hot Number, and Pattern.

What is a semi-auto lotto combiner?

A semi-auto lotto combiner lets you select just 1 to 4 key numbers, after which one of 4 heuristic algorithms (Balanced, Random, Hot Number, Pattern) automatically fills in the remaining numbers. The Balanced algorithm produces combinations balanced across odd/even, high/low, and number ranges; Random produces fully random combinations; Hot Number focuses on numbers drawn frequently in recent draws; and Pattern analyzes past winning patterns to build combinations. It is handy when you have key numbers you definitely want to include but prefer to leave the rest to an algorithm, or when you want to compare combinations of different styles across multiple algorithms.

What is AC (Arithmetic Complexity)?

AC (Arithmetic Complexity) is an indicator that expresses the diversity of a lottery number combination. It calculates the difference between each pair of numbers and counts how many unique differences there are. For example: [1, 2, 3, 4, 5, 6] → differences: 1,2,3,4,5 → AC=5 / [1, 11, 21, 31, 41, 45] → differences: 4,10,14,20,24,30,40,44, etc. → AC=13. Generally, the higher the AC value, the more evenly the numbers are distributed, while the lower the AC value, the more consecutive or regular the numbers are.
