Spin Jam Summary

are two clockwise and counterclockwise spirals for each starting point. A point set (left), and its clockwise convex helix, with the smallest x-coordinate point as the initial point. Interestingly, the convex helix and onion skins of a point set can be converted to each other in linear time. Further, similar to the onion triangulation, we can define a sub-graph of a point set as a spiral triangulation of a

Comparative analysis of common software development models

practice of software development shows that the above activities are not completely top-down and linear schema, so the waterfall model has serious defects.① because the development model is linear, users cannot see the effect of the software when the development results have not been tested. This allows the software to meet the user for a long time interval, but also increased a certain amount of risk.② errors found during the end of software development are propagated to later development acti
