Every single instance of altruistic behavior need not always increase inclusive fitness ; altruistic behaviors would have been selected for if such behaviors on average increased inclusive fitness in the ancestral environment.

Every lattice element of the structure is in its proper place, whether it is a single atom or a molecular grouping.

Every single thermodynamic system exists in a particular state.

* Every pair of congruence relations for an unknown integer x, of the form x ≡ k ( mod a ) and x ≡ l ( mod b ), has a solution, as stated by the Chinese remainder theorem ; in fact the solutions are described by a single congruence relation modulo ab.

Group actions / representations: Every group G can be considered as a category with a single object whose morphisms are the elements of G. A functor from G to Set is then nothing but a group action of G on a particular set, i. e. a G-set.

Every singleton is a terminal object, with the functions mapping all elements of the source sets to the single target element as morphisms.

Every quark in the universe does not attract every other quark in the above distance independent manner, since colour-confinement implies that the strong force acts without distance-diminishment only between pairs of single quarks, and that in collections of bound quarks ( i. e., hadrons ), the net colour-charge of the quarks cancels out, as seen from far away.

Every stalactite begins with a single mineral-laden drop of water.

: Every single week,

Every non-empty intersection of a 3-sphere with a three-dimensional hyperplane is a 2-sphere ( unless the hyperplane is tangent to the 3-sphere, in which case the intersection is a single point ).

Every single letter was returned with a minimum of $ 1, 000 in donation.

Marr told NME in early 1987, " Every single label came to see us.

The dark theme of the album was balanced by " Every Little Thing ", a " celebration of what a wonderful girl the guy has ", according to Unterberger, that appeared later in the album and had been written as an attempt for a single, according to McCartney:

", " Eight Days a Week " ( a number one hit single in the US in early 1965 ), " What You're Doing ", " Words of Love ", " Every Little Thing ", and " I Don't Want to Spoil the Party " ( flipside to " Eight Days a Week ", it reached number 35 in the US and it would hit number one on the US Country chart for Rosanne Cash when she remade it in 1989 ).

This problem is encapsulated in the phrase " Every selection of one is a rejection of many ".

Every human advance solves one problem but also engenders another.

Every three years the College also holds a ball, usually off site due to the problem of securing the college's perimeter sufficiently for insurance purposes. The most recent off-site ball was held was February 9, 2008 at Heythrop Park.

Every CSP can also be considered as a conjunctive query containment problem.

Every closed 3-manifold has a prime decomposition: this means it is the connected sum of prime three-manifolds ( this decomposition is essentially unique except for a small problem in the case of non-orientable manifolds ).

* Every positive integer can be written as the sum of 73 or fewer sixth powers ( see Waring's problem ).

Every positive integer is the sum of at most 37 fifth powers ( see Waring's problem ).

Every linear program has a dual problem with the same optimal solution, but the variables in the dual problem correspond to constraints in the primal problem and vice versa.

Every positive integer can be expressed as the sum of at most 19 fourth powers ; every sufficiently large integer can be expressed as the sum of at most 16 fourth powers ( see Waring's problem ).

Every graph ( that is connected and not a tree ) has multiple spanning trees, so we once again have an example where the problem itself allows multiple possible outcomes, and the algorithm chosen can arrive at any one of them, but will never arrive at something else.

Every non-trivial problem in L is complete under log-space reductions so weaker reductions are required to identify meaningful notions of L-completeness, the most common being first-order reductions.

# Every solution to a wicked problem is a " one-shot operation "; because there is no opportunity to learn by trial and error, every attempt counts significantly.

# Every wicked problem is essentially unique.

# Every wicked problem can be considered to be a symptom of another problem.

# Every wicked problem is essentially novel and unique.

# Every solution to a wicked problem is a ' one shot operation.

Russell L. Ackoff wrote about complex problems as messes: " Every problem interacts with other problems and is therefore part of a set of interrelated problems, a system of problems ….
