"highly random" is both grammatically correct and commonly used in written English.
It is typically used to describe something that is random to a high degree or with a strong level of unpredictability. Example: The results of the experiment were highly random, making it difficult for the researchers to draw any definitive conclusions.
Based on the highly random fracture patterns generated via sonication, we conclude that the tubes are composed of amorphous SiO2.
Throughout the vast majority of the N.F.L., turnovers are highly random.
"Unfortunately with this unfolding security environment, which is highly random and highly irrational, you don't know whether you're going to be able to bring anything on board".
A major effort of theoretical physics today is to understand highly random phenomena like clouds, air turbulence and fire in terms of fractal geometry.
On channels that are not highly random (e.g., free space wireless or wire-line), near capacity performance is achievable in a complexity that is implementable with modern technology.
However, the evacuation process is a highly random phenomenon that is subject to the variability of human behaviours and other risk factors pertaining to an emergency.
Highly random-seeming sequences should uniquely map while non-random sequences, for example, a sequence with mostly Ts, will map ambiguously or be discarded since the string of Ts could map to many portions of the genome that have Cs at indeterminate locations in the string of Ts.
In case of highly-random textured area, no matching can be found between blocks and vertical interpolation is preferred, and some blurring is introduced.
The article focused on the Russian leader's cynical annual "Direct Line" televised call-in show, which serves to deflect criticism and attention from his cruel and corrupt authoritarian regime through a few highly publicized "random acts of kindness". There is, of course, nothing at all random about this.
To generalise the notion of randomness, as proposed above, permits highly non-random sequences to be called random as long as they reflect the chances of highly biased processes.
Random-digit dialled telephone numbers and within-household random-sampling grids (Kish grids) are a cost-effective way to survey highly representative random population samples.
