- de.tilman_neumann.jml.factor.cfrac.tdiv.TDiv_CF63_01

All Implemented Interfaces:

TDiv_CF63
```
public class TDiv_CF63_01
extends Object
implements TDiv_CF63
```
Auxiliary factor algorithm to find smooth decompositions of Q's. Version 01: Uses only trial division -> this means that partials can have only 1 big factor

Modifier and Type	Method	Description
`String`	`getName()`
`void`	`initialize(BigInteger N, double maxQRest)`	Initialize for a new N.
`void`	`initialize(BigInteger kN, int primeBaseSize, int[] primesArray)`	Initialize this factorizer for a new k; in particular set the prime base to be used for trial division.
`AQPair`	`test(BigInteger A, long Q)`	Check if Q is smooth (factors completely over the prime base) or "sufficiently smooth" (factors almost over the prime base).
