The phrase "a population of virtual" is correct and usable in written English.
It can be used in contexts discussing digital environments, online communities, or simulations where a group of virtual entities or characters is being referenced.
Example: "In the game, players can interact with a population of virtual characters that respond to their actions in real-time."
Alternatives: "a group of virtual" or "a community of virtual".
From a theoretical viewpoint, the artificial pancreas has been designed by suitably exploiting a minimal set of delay differential equations modeling the glucose insulin regulatory system; on the other hand, the validation platform makes use of a different, multi-compartmental model to build up a population of virtual patients.
For example, in one computer activity, described below, students were able to discover through experimentation that a population of virtual plants was able to adapt, over many generations, to gradual changes in their environment eventually evolving into very different-looking organisms.
Typically, in evolutionary simulation experiments a population of virtual organisms is evolved using a genetic algorithm [11] over many generations to best survive in a given environment.
We generated a population of 65 virtual patients with the close-to-ideal dosage strategy for each of them.
The proposed DD-MPC was evaluated on a population of 500 virtual patients recorded for 168 hours (1 week) by hourly measurements of P, N , D and CA. In the case when treatment is not applied, the population has 85 septic, 117 aseptic, and 298 healthy virtual patients.
In a manner similar to that of Rastogi et al. [ 11], a population of 1,000 virtual organisms containing a single copy of the SAP protein [ 25] (PDB ID: 1D4T) was evolved for 200,000 generations at a rate of 10-5 mutations per bp per generation at the DNA level, with transitions being twice as probable as tranversions.
The results show the robustness of the proposed control law that turns out to be efficient and extremely safe on a heterogenous population of virtual patients.
Thus, when the ancestor is used to begin a population of Avidians in the virtual Petri dish, and a mutation rate is set, random variation is introduced into the resulting Avidian population during replication (Fig. 1b).
These results have encouraged the application and the improvement of the GA for the seek of the optimum vaccination protocol as, at the state of the art, the mentioned vaccination schedules did not prevent the cancer cells to reach an unsafe growth level and, moreover, did not protect a large percentage of our population of virtual mice.
It will be based around a single-player environment called "Homeworld", where players sculpt the landscape with their fingers, and oversee their growing population of virtual inhabitants.
The registered population of virtual worlds (even if this is not the same as active users) is greater than the populations of the US and Europe combined.
