Many practical problems are actually " easy ", so the SAT solver can easily find a solution, or prove that none exists, relatively quickly, even though the instance has thousands of variables and tens of thousands of constraints.

Many other decision problems, such as graph coloring problems, planning problems, and scheduling problems, can be easily encoded into SAT.

Many people with dyslexia have auditory processing problems and may develop their own logographic cues to compensate for this type of deficit.

Many were seen as reflections of broad underlying conflicts or maladaptive reactions to life problems, rooted in a distinction between neurosis and psychosis ( roughly, anxiety / depression broadly in touch with reality, or hallucinations / delusions appearing disconnected from reality ).

Many different problems are addressed, like foreign policy, declarations of war, the legitimacy of leaders, and the introduction of new ideas and laws.

Many mutations arise as a result of problems caused by the DNA lesions during replication, resulting in errors in replication.

Many common health problems can be prevented or alleviated with a healthy diet.

Many natural computer science problems are covered by the class NP.

Many things can happen to packets as they travel from origin to destination, resulting in the following problems as seen from the point of view of the sender and receiver:

Many of the issues that he takes on in these books have to do with the kinds of problems that adolescents experience.

According to anthropologists John Monaghan and Peter Just, Many of the great world religions appear to have begun as revitalization movements of some sort, as the vision of a charismatic prophet fires the imaginations of people seeking a more comprehensive answer to their problems than they feel is provided by everyday beliefs.

Many Australian and UK soap operas explore social realist storylines such as family discord, marriage breakdown, or financial problems.

Good service starts with product design and planning: Many products seem to be designed for a production economy, not for a service one.

Many statisticians base ANOVA on the design of the experiment, especially on the protocol that specifies the random assignment of treatments to subjects ; the protocol's description of the assignment mechanism should include a specification of the structure of the treatments and of any blocking.

Many architects elect to move into real estate ( property ) development, corporate facilities planning, project management, construction management, interior design or other related fields.

Many modern moorings still rely on a large rock as the primary element of their design.

Many small engines, such as those found in mopeds or garden machinery, are single cylinder and use only a single piston, simplifying crankshaft design.

Many early aircraft engines ( and a few in other applications ) had the crankshaft fixed to the airframe and instead the cylinders rotated, known as a rotary engine design.

Many years later these alpha versions were sanctioned by id Software because of historical interest ; they reveal how the game progressed from its early design stages.

Many overlapping methods and processes can be seen when comparing Product design, Industrial design and Engineering.

Many design ideas for the language came from Craig's Master's Thesis in Computer Science at the University of Toronto.

Many graffiti artists have used their design talents in other artistic endeavors.

Many building codes specify basic foundation design parameters for simple conditions, frequently varying by jurisdiction, but such design techniques are normally limited to certain types of construction and certain types of sites, and are frequently very conservative.

Many of the techniques of CPU and OS design that improve interrupt latency will decrease throughput and increase processor utilization.

Many modern kayaks have modified the traditional design in various ways, such as: eliminating the cockpit by seating the paddler on top of the boat (" sit-on-top " kayaks ); having inflated air chambers surrounding the boat ; replacing the single hull by twin hulls (" W " kayak ), and replacing paddles with other human powered propulsion methods, such as foot-powered rotational propellers and ' flippers '.

Many components of normal electronic design are available in a microelectronic equivalent.

Many aspects of modernist design still persist within the mainstream of contemporary architecture today, though its previous dogmatism has given way to a more playful use of decoration, historical quotation, and spatial drama. In other arts such pragmatic considerations were less important.

Many other modern machine guns, including the US M60 and the FN MAG borrow elements of the design of the MG42.

Many Mesa programmers and developers left Xerox in 1985 ; some of them went to DEC Systems Research Center where they used their experience with Mesa in the design of Modula-2 +, and later of Modula-3.

Many layout builders are choosing digital operation of their layouts rather than the more traditional DC design.

Many web design tutorials also point out that client-side redirecting tends to interfere with the normal functioning of a Web browser's " back " button.

Many consumer products, such as automobiles and consumer electronics, use reliability theory in product design to reduce the probability of failure.

Many other paradigms are supported using extensions, including design by contract and logic programming.

Many other fields in the production engineering and design engineering and heavy industrial have project managers.
