  "Description": "An implementation of the algorithm described in \"Efficient\nLarge- Scale Internet Media Selection Optimization for Online\nDisplay Advertising\" by Paulson, Luo, and James (Journal of\nMarketing Research 2018; see URL below for journal\ntext/citation and\n<http://faculty.marshall.usc.edu/gareth-james/Research/ELMSO.pdf>\nfor a full-text version of the paper). The algorithm here is\ndesigned to allocate budget across a set of online advertising\nopportunities using a coordinate-descent approach, but it can\nbe used in any resource-allocation problem with a matrix of\nvisitation (in the case of the paper, website page- views) and\nchannels (in the paper, websites). The package contains\nallocation functions both in the presence of bidding, when\nallocation is dependent on channel-specific cost curves, and\nwhen advertising costs are fixed at each channel.",
