Unsolvable

There are times when it seems like an unsolvable problem, so it is important to sign on to any possible solution — even when it comes in the form of a policy proposal or legislative stance.

Above all else, however, something unsolvable emerged between the basic objective of maintaining the security zone on behalf of the security of the northern Israeli communities and the need to defeat Hezbollah.

I hate how the SAPS are making the Senzo Meyiwa case looks like some hard unsolvable case.

Maybe the concussion crisis and player safety is an unsolvable riddle, but the NFL has become a model of inconsistency and hubris.

Op-Ed: Joe Biden seems to think school segregation is nearly unsolvable.

With a quantum coprocessor in the cloud, physicists have opened the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics.

But Israel is the ultimate elusive and unsolvable Rubik’s Cube.

It only reinforces mentalities of rape culture and a culture of violence against women, which treat these things as unsolvable societal norms that women must accept the entire burden of navigating daily.

Others argue that the country should not get lost in an unsolvable disagreement on the science but rather just talk about solutions.

Although the Bohr model of the hydrogen atom could be explained in this way, the spectrum of the helium atom (classically an unsolvable 3-body problem ) could not be predicted.

As a consequence, for each CNF formula, it is possible to solve the XOR-3-SAT problem defined by the formula, and based on the result infer either that the 3-SAT problem is solvable or that the 1-in-3-SAT problem is unsolvable.

As a result of its unsolvability, several other problems in combinatorial group theory have been shown to be unsolvable as well.

Church and Turing independently demonstrated that Hilbert's Entscheidungsproblem (decision problem) was unsolvable, citation thus identifying the computational core of the incompleteness theorem.

He suggests that these issues, "while not unsolvable, are formidable," and that the literature might be improved by better introspection and criticism of PRT.

He works in the X-Files office, which is concerned with cases marked as unsolvable; most involve supernatural/mysterious circumstances.

History A Penrose tiling In 1961, Hao Wang asked whether determining if a set of tiles admits a tiling of the plane is an algorithmically unsolvable problem or not.

Hodges p. 91 As late as 1930, he believed that there would be no such thing as an unsolvable problem.

In other words the uniform word problem for the class of all finitely presented groups with solvable word problem is unsolvable.

It is fundamentally different from most solitaire games in that very few hands are unsolvable. citation Although software implementations vary, most versions label the hands with a number (derived from the random number seed used to generate the hand).

It is said that unification is semi-decidable for a theory, if a unification algorithm has been devised for it that terminates for any solvable input problem, but may keep searching forever for solutions of an unsolvable input problem.
