Rather, such assignments are made, as they must be, on the basis of certain overall rules and standards, representing to some extent a statistical approach to the problem, taking into account for each situation some of the variables ( e.g., power and station separations ) and averaging out others in order to achieve the balance which must be struck between protection against destructive interference and the assignment of a number of stations large enough to afford optimum radio service to the Nation.

The solution to this problem yields a Pareto optimum.

The optimum of the simultaneous problem is superior to the design found by optimizing each discipline sequentially, since it can exploit the interactions between the disciplines.

Also, no existing solution method is guaranteed to find the global optimum of a general problem ( see No free lunch in search and optimization ).

A local optimum of a combinatorial optimization problem is a solution that is optimal ( either maximal or minimal ) within a neighboring set of solutions.

optimized, local search effectively solves the problem: finding a local optimum delivers

For Self Actualization the manager needs to promote the optimum workplace through morality, creativity, spontaneity, problem solving, lack of prejudice, and acceptance of facts.

The user optimum equilibrium can be found by solving the following nonlinear programming problem

Tolkowsky's guidelines, while revolutionary in their day, are not a definitive solution to the problem of finding the optimum proportions of a round brilliant cut diamond.

Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium ( such as a rocket or aircraft, missile or bullet ), an important problem is the determination of the nose cone geometrical shape for optimum performance.

A great deal more study of the problem and of the optimum system design should precede the commitment to fund the search program.

Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium ( such as a rocket or aircraft, missile or bullet ), an important problem is the determination of the nose cone geometrical shape for optimum performance.

The problem is computationally difficult ( NP-hard ), however there are efficient heuristic algorithms that are commonly employed and converge fast to a local optimum.

Part of the economic theory of public goods is that they would be under-provided ( at a rate lower than the ‘ social optimum ’) because individuals had no private motive to contribute ( the free rider problem ).

The problem can be extended to three or more people, but the method for finding an optimum solution becomes complicated.

After this brief discussion of neo-, paleocortical, and cortico-hypothalamic relations, let us return once more to the problem of hypothalamic balance and its physiological and pathological significance.

As an illustration of this problem, when official data for all the world's countries are added up, exports exceed imports by almost 1 %; it appears the world is running a positive balance of trade with itself.

For example, the second edition of the popular introductory textbook, An Outline of Money, devoted the last three of its ten chapters to questions of foreign exchange management and in particular the ' problem of balance '.

The Swedish industry did not have this problem, as its production was more in balance with the market, and more importantly, the quality of its films was now superior to those from Denmark.

The environmental issues is a great problem for the nature and nation of Pakistan and has been disturbing the balance between economic development and environmental protection.

Although the use of offset crankpins, counterweights, and flying arms has reduced the problem to a minor second-order vibration in modern designs, all V6s can benefit from the addition of auxiliary balance shafts to make them completely smooth.

The NLTC solves the problem that the basic LTC method underestimates the trick taking potential by one on hands with a balance between ' ace-losers ' and ' queen-losers '.

It is a problem of societal communication and coordination to balance costs and benefits.

As with external costs, there is a problem here of societal communication and coordination to balance benefits and costs.

With any kind of alarm, the need exists to balance between on the one hand the danger of false alarms ( called " false positives ") — the signal going off in the absence of a problem — and on the other hand failing to signal an actual problem ( called a " false negative ").

The lack of natural resources meant that East Pakistan was heavily dependent on imports, creating a balance of payments problem.

Along with a trade imbalance and balance of payment problem, its need for credit to finance its budget deficits made Argentina's economy vulnerable to economic crisis and instability.

As pH 7 is essentially, a " zero point " calibration ( akin to zeroing or taring a scale or balance ), calibrating at pH 7 first, calibrating at the pH closest to the point of interest ( e. g. either 4 or 10 ) second and checking the third point will provide a more linear accuracy to what is essentially a non-linear problem.

The primary physician may request the opinion of an otolaryngologist to help evaluate a balance problem.

One option includes treatment for a disease or disorder that may be contributing to the balance problem, such as ear infection, stroke, multiple sclerosis, spinal cord injury, Parkinson ’ s, neuromuscular conditions, acquired brain injury, cerebellar dysfunctions and / or ataxia.

In order to delay the problem, manufacturers bias the colour balance towards blue so that the display initially has an artificially blue tint, leading to complaints of artificial-looking, over-saturated colors.

Khalilzad sought political solutions to the problem of sectarianism, in particular working to integrate the balance of power between Iraq's three main ethic groups in order to head off growing Sunni violence.

The more common inline-4 configuration suffers from an engine balance problem caused by the fact that the pistons travel faster on the top half of the crankshaft rotation than the bottom half, which causes the engine to vibrate up and down twice per crankshaft revolution.

This problem becomes worse with increased engine size and power so inline-4s larger than 2. 0 L usually have balance shafts and ones over 3. 0 L are seldom used in passenger cars.

Margaret Cox and Simon Mays sum up the position: " Although it can hardly be said that craniometric data provide an unequivocal answer to the problem of the Beaker folk, the balance of the evidence would at present seem to favour a migration hypothesis.

The inverted pendulum has been employed in various devices and trying to balance an inverted pendulum presents a unique engineering problem for researchers.

Equations governing a linear elastic boundary value problem are based on three tensor partial differential equations for the balance of linear momentum and six infinitesimal strain-displacement relations.
