We study a primitive vehicle routing-type problem in which fleet of n unit speed robots start from point within non-obtuse triangle $$\Delta $$ , where $$n \in \{1,2,3\}$$ . The goal is to design robots’ trajectories so as visit all edges the with smallest visitation time makespan. begin our by introducing framework for subdividing into regions respect type optimal trajectory that each P admits...

The World Health Organization’s (WHO’s) World Health Report 2010, “Health systems financing, the path to universal coverage,” promoted universal health coverage (UHC) as an aspirational objective for country health systems. Yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...

Local adaptation is considered to be the result of fitness trade-offs for particular phenotypes across different habitats. However, it is unclear whether such phenotypic trade-offs exist at the level of individual genetic loci. Local adaptation could arise from trade-offs of alternative alleles at individual loci or by complementary sets of loci with different fitness effects of alleles in one ...
