Maulik–Pandharipande's conjecture on Gromov–Witten invariants of blow-ups

Let $X$ be a smooth variety, let $Z\subset X$ be a complete intersection of $l$ divisors $W_1,\ldots,W_l$ of $X$, and let $\widetilde X$ be the blow-up of $X$ along $Z$. Maulik–Pandharipande's conjecture. The descendent absolute Gromov–Witten invariants of $\widetilde X$ are determined by the restriction map

$$H^*(X)\rightarrow H^*(Z)$$

and the descendent absolute Gromov–Witten invariants of $X$ and $Z$. This conjecture concerns the determination of Gromov–Witten theory under blow-up along a complete intersection; the surrounding discussion states that it has alternative proofs, so it is treated as solved.
