aliasing (IAA)[5] which produces reliable anti aliased ray traced image of implicit surfaces. This method evaluates ar-eas of the pixel instead of points as in point sampling. In-terval arithmetic is used to guarantee that small parts of the surfaceseenthroughthepixelarenotmissed. Thesetofrays that cover an area of the pixel are treated as a unique beam.

antialiasing of rasterized images with adaptive ray traced supersampling. Offline ray tracing renderers have long employed highly adaptive sample counts to solve aliasing (e.g., Whitted’s original paper [26]), but until now hybrid ray and raster algorithms [2] have been impractical for real-time rendering due to the duplication

putational time in the entire ray tracing process. The quality of the visualization is improved by means of the creation of an adaptive anti aliasing algorithm. Using this strategy, it is possible to evaluate areas of the pixels instead of points. The efficiency of animated scenes composed by implicit surfaces is also improved. The improvement is

You could even do temporal anti aliasing in ray tracing for instance. Julien expanded on Raxvan's 2nd item which was an explanation of super sampling, and showed how you'd actually do that, also mentioning that you can randomize the location of the samples within the pixel but then you are entering signal processing country which is a lot ...
Anti-aliased and accelerated ray tracing

Antialiasing in a ray tracer. We would like to compute the average intensity in the neighborhood of each pixel. When casting one ray per pixel, we are likely to have aliasing artifacts. To improve matters, we can cast more than one ray per pixel and average the result. A.k.a., super-sampling and averaging down.
