The current state of the art for rooted phylogenetic networks, on the other hand, can be characterized as follows: there are many promising directions to follow and some rudimentary software implementations (Huber et al., 2007; Than et al., 2008; van Iersel and Kelk, 2008).
Moreover, although our implementation was rudimentary in comparison with CPLEX 6.0, a commercial solver, the tested methods were competitive (sometimes favorable) in attaining a final (though only near optimal) solution for the set of large-scale low-density problems.
This first implementation is fairly rudimentary, at best, but it's still pretty impressive for a DIY effort.
Graphics could also be optimized using CSS sprites, etc. Regarding caching the LiU EEE implementation contains a rudimentary in-memory cache but can also be configured to use Memcache if such servers are available.
A rudimentary HTTP-based test suite for testing implementations based on this design approach has been started, but it could get expanded to cover all the parts in a future openEHR Service specification for REST.
In many developing country settings, and particularly in rural areas, the implementation of anything more than very rudimentary contracts for medical care providers, including public employees, is virtually impossible.
Colour although an important characteristic is often avoided in place of faster grey-scale implementations or is only used in an rudimentary arrangement.
We have highlighted in this paper some of the rudimentary problems in variant annotation that are hindering the large-scale implementation of genomic medicine that NGS is poised to deliver.
The initial implementation of an EHR is often rapidly followed by naïve attempts to implement and use rudimentary forms of CDS (e.g., a hard stop for drug-drug interaction alerts).
Some other limiting factors include use of rudimentary simulation environment modeling with several of the critical technical features missing from the implementation of both standards.
