Fast exponentiation in java

WebSummary: The two fast Fibonacci algorithms are matrix exponentiation and fast doubling, each having an asymptotic complexity of Θ(logn) bigint arithmetic operations. Both algorithms use multiplication, so they become even faster when Karatsuba multiplication is used. The other two algorithms are slow; they only use addition and no multiplication. WebWe formulate the fast exponentiation strategy as an algorithm. Instead of first going through the repeated squaring and then multiplying the needed powers we combine the two steps in one loop. In this loop we square and at the same time compute whether or not that power of two is used in the exponent as a sum of powers of two. 🔗 Algorithm 15.3.5.
