A skew binomial heap (or skew binomial queue) is a variant of the binomial heap that supports worst-case O(1) insertion, rather than the O(lg n) worst-case insertion from the original binomial heap. Just as binomial heaps are based on the binary number system, skew binary heaps are based on the skew binary number system.[1]
