Exempel på hur du använder UNSOLVABLE i en mening

• It is fundamentally different from most solitaire games in that very few deals are unsolvable, and all cards are dealt face-up from the beginning of the game.
• Often regarded as one of the greatest mathematicians of all time, though he had almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions, including solutions to mathematical problems then considered unsolvable.
• They were followed by Tarski's undefinability theorem on the formal undefinability of truth, Church's proof that Hilbert's Entscheidungsproblem is unsolvable, and Turing's theorem that there is no algorithm to solve the halting problem.
• Since the mathematical problems stemming from nontrivial fleet scheduling easily become computationally unsolvable, the PONTIFEX idea consisted in a seamless merge of algorithms and heuristic knowledge embedded in rules.
• Some abstract problems have been rigorously proved to be unsolvable, such as squaring the circle and trisecting the angle using only the compass and straightedge constructions of classical geometry, and solving the general quintic equation algebraically.
• A perfect crime is a crime that is undetected, unattributed to an identifiable perpetrator, or otherwise unsolved or unsolvable.
• Random instances undergo a sharp phase transition from solvable to unsolvable instances as the ratio of constraints to variables increases past 1, a phenomenon conjectured but unproven for more complicated forms of the satisfiability problem.

• there is a constant N such that, given a Diophantine equation with any number of parameters and in any number of unknowns, one can effectively transform this equation into another with the same parameters but in only N unknowns such that both equations are solvable or unsolvable for the same values of the parameters.

• This is the epochal paper where Turing defines Turing machines, shows that the Entscheidungsproblem is unsolvable.
• The individual exercising reason should remain aware of the crisis of reason and see the antinomy, those rationally unsolvable contradictions that reason unearths, as the basis for personal renewal.
