Pareto optimality

a theoretical condition of the economy in which the distribution of economic welfare cannot be improved for any one individual without reducing the welfare of one or more other individuals. Thus a ‘Pareto improvement’ occurs when a reallocation of resources renders one or more persons better off. In any situation where more than one optimum is possible, Pareto optimality cannot be established.

The Pareto improvement strategy is based on the Pareto improvement scheme which can lead to Pareto optimality on this problem, so this algorithm can always give an optimum utility function under different distances between vehicles and the associated RSU.
The Pareto frontier is the graphical representation of the Pareto optimality conditions by showing the front of all the nondominated solutions.
It should be noted that Pareto optimality can be also considered by starting from a family [{[[??].sub.i]}.sub.i[member of]{1, ..., m}] of not necessarily total preorders on a set X (see, e.g., d'Aspremont and Gevers [11]).
Thus, in the absence of preference information on the objectives, the concept of Pareto optimality is adopted in this study for solving multiobjective optimization problems [24] and several definitions about Pareto optimality [20,25,26] are considered and stated below.
This belief is based on a principle called "Pareto optimality," which assumes that the people who gain higher incomes can always compensate the losers.
(2014) used Normal Boundary Intersection (NBI) and BDA for their multi-objective framework; however, one drawback of the combined NBI algorithm is that Pareto optimality solution is not guaranteed (Das & Dennis, 1998; Ghane-Kanafi & Khorram, 2015).
These new algorithms introduced the concept of Pareto optimality into the selection process which awarded them a great success in application to various disciplines of engineering as thoroughly described in [8].
Pareto Optimality. Normally, objectives are restricted or conflicting with each other [38], which results in the global optimum solution being not unique.
On the basis of previous studies [28, 34, 35], we adopt Pareto optimality to find the practical optimal solution.
Pareto Optimality. Let M be some finite set and let f : M [right arrow] [R.sup.t] be an objective function to minimize.
The first theorem of welfare economics is Pareto optimality, which states that an economy is in an equilibrium constituting optimum welfare when all exchanges of goods between economic actors have taken place, this being identified by the impossibility of a reallocation of goods that would not leave at least one actor worse off.
In economic terminology, the term "efficiency" refers to the idea of Pareto optimality, or, alternatively, to other concepts (such as Kaldhor-Hicks efficiency and social welfare maximization) commonly used in policy analyses to overcome the restricted practicability of the Pareto efficiency criterion.
