EnumerationCurves is a package to compute the physical numbers of rational curves on Calabi-Yau threefolds via torus actions.
The implementation uses the formulas given in the paper of Kontsevich "Enumeration of rational curves via torus actions".
The main idea is to apply the localization theorem of Atiyah and Bott to reduce the computation to integrations over graphs.
