I'm new to Function Field Sieve(FFS) (Number Field Sieve(NFS) as well) method and I'm finding it is quite difficult to understand it (especially concepts of valuation at infinity, Ca,b curves etc.)
I have read these papers:
For NFS luckily i got this book : Chapter 11 NFS (Algebraic Number Theory : Frazer Jarvis )
He presented NFS by working example(including factorbase construction on both Algebraic and Rational side and many other things).
But for FFS I searched a lot but didn't find any example and it is very difficult to grasp its concept by theory only. Please if anyone can refer or give working example of FFS, it will be very helpful.
