comment Symplectic sum and Symplectic cut
Thanks, I finally wrote it myself. At least in one direction, the main point is the Exercise 3.36 of McDuff-Salamon

comment genus one Gromov-Witten invariants of Calabi-Yau 3-folds
Thanks for sharing, I appreciate it. People can go through the link and study his answer. I found his answer somewhat problematic, I may suggest some reviews to him later. There is also some recent talk by Aleksey Zinger in Simons center which is related to the subject, I would share the link some time later.

comment Intersection theory on M_{g,n}
I am aware of a Macaulay based program doing this but I am looking for some printed numbers.

comment almost holomorphic line bundles
Thanks for sharing your thoughts. I agree with the first paragraph on how the question can be stated. Then in fact, my question is about the existence of a good J_M; generic J_M does not have this property for sure. I am looking for topological or symplectic obstructions against the existence of such J_M. For example, chern class of L is a well-defined 2-form no matter what J is. Then what does the existence of such J impose on this class; if J_M is good, can we conclude that c_1(L) would be (1,1) with respect to J_M? and similar.
