biological research of all kinds on mosquitoes must be built upon a foundation of correct identification and sound classification. except for the anopheline vectors of malaria, relatively little is known about other mosquitoes in iran and other countries in southwest asia. in view of this a comprehensive study on the mosquito fauna of iran has started since 1981. in this report the list of the ...

Clearly, the optimum objective value of (P’) is at most μ̃s(G) because any relaxed s-t-cut c : V → [0, 1] induces a feasible solution with objective value size(c) by defining xv := c(v) for all variables xv. Conversely, every feasible solution x for (P’) induces a relaxed s-t-cut c by defining c(v) := xv for all v ∈ V. We conclude that the optimum objective value of (P’) is at least (and therefo...
