A slightly larger count ( but still better than split radix for N ≥ 256 ) was shown to be provably optimal for N ≤ 512 under additional restrictions on the possible algorithms ( split-radix-like flowgraphs with unit-modulus multiplicative factors ), by reduction to a Satisfiability Modulo Theories problem solvable by brute force ( Haynal & Haynal, 2011 ).

Theories could be divided into two categories: top-down and bottom-up.

Theories more favorable to corporate activities may be praised using the term " sound science ".

Theories may be expressed mathematically, symbolically, or in common language, but are generally expected to follow principles of rational thought or logic.

He later regarded it as a flawed exposition of his logical system, and wanted An Investigation of the Laws of Thought ( 1854 ), on Which are Founded the Mathematical Theories of Logic and Probabilities to be seen as the mature statement of his views.

Theories or models can be more readily tested.

Theories for this warming include a change of frost patterns on Triton's surface and a change in ice albedo, which would allow more heat to be absorbed.

Theories about the origin of the city's name suggest that it may be a corruption of the Spanish la virgen, after the nearby Virgin River, or possibly an error in the transcription of the term " beaver skin.

Theories of secession address a fundamental problem of political philosophy: the legitimacy and moral basis of the state's authority, be it based on " God's will ", consent of the people, the morality of goals, or usefulness to obtaining goals.

However, by developing explicit processes that generate change from individuals, groups or communities ( Theories of Change ), and by fusing political economy analysis and outcome mapping tools, the complex state-citizen dynamics can be better understood.

Theories of collective action emphasise how group behavior can, in some sense, be linked to social institutions.

The boolean satisfiability problem ( SAT ), the Satisfiability Modulo Theories ( SMT ) and answer set programming ( ASP ) can be roughly thought of as certain forms of the constraint satisfaction problem.

Theories of the middle range should be firmly supported by empirical data.

Theories, some of them rather bizarre, abound: some contemporary scholars suggest, for example, that the persona may be a woman ; if so, the strangulation could stem from frustration with the world.

Theories that predict the formation of these structures within the observable universe ( see: inflation ) can therefore be largely ruled out.
