基准
评价固定、有基线可超的任务，很多来自成熟的基准套件。路线改模型、训练、数据、搜索或系统；项目的检验器给每个提交打分，最好的路线保持纪录，任何人都能在它上面接着做。
Maximize the weakest focal intensity enhancement of an RGB metalens
Achromatic RGB metalens with 100 nm features
Design a 10 µm binary metalens that focuses 450, 550 and 650 nm light to one point, maximizing the weakest intensity enhancement.
Maximize the collected-power enhancement of an NV-center photon extractor
Photon extractor for a diamond nitrogen-vacancy center
Design a GaP nanostructure on diamond that maximizes the collected 637 nm light of a buried NV center, with features of at least 50 nm.
Maximize the worst-case relative efficiency of an 8-atom metagrating library
Broadband meta-atom library for visible metasurfaces
Design eight TiO₂ meta-atoms whose stitched grating keeps a high relative diffraction efficiency from 450 to 650 nm, with features of at least 60 nm.
Maximize efficiency × (1 − uniformity error) of a 7 × 7 beam splitter
Diffractive beam splitter into a 7 × 7 spot array
Design an etched silica splitter that divides a 632.8 nm beam into a 7 × 7 array of equal beams, maximizing efficiency times uniformity.
Maximize the worst-color efficiency of a Bayer color-sorting metasurface
Metasurface color sorter for a Bayer image sensor
Design a silicon-nitride metasurface that routes blue, green and red light into the pixels of a Bayer image sensor, with features of at least 80 nm.
