    • n adversary Synonyms and Adversary, Antagonist, Opponent, Enemy, Foe. These words vary in strength according as they express spirit, action, or relation. A foe has most of the spirit of enmity, or is actively hostile. The word is more used in poetry than in prose. Enemy, as denoting an opponent in war, or a member of an opposing party, does not necessarily imply personal hostility. Opponent, adversary, and antagonist are less severe in their opposition, and need have no animosity. Opponent is often a passive word; antagonist is always active and personal. A man may be our opponent in an argument or a lawsuit, our adversary in a game, as chess, our antagonist in a wrestling- or boxing-match, or other occasion of strenuous exertion: the choice between the three words depends chiefly upon the measure of activity involved. In the Bible, adversary covers the meaning of all five words.
    • adversary To antagonize; oppose.

In science:

The decoder does not know pY|XSa selected by the adversary and has access to Sd .
Capacity and Random-Coding Exponents for Channel Coding with Side Information
We allow the encoder/decoder pair (fN , gN ) to be randomized, i.e., the choice of (fN , gN ) is a function of a random variable known to the encoder and decoder but not to the adversary.
Capacity and Random-Coding Exponents for Channel Coding with Side Information
We do not follow this approach because pS a |S e is fixed and pY|XSa is optimized by the adversary; hence these p.m.f.’s appear separately in the problem formulation and its solution. A similar comment applies to Sd .

Capacity and Random-Coding Exponents for Channel Coding with Side Information
The case of channels with arbitrary memory sub ject to expected-distortion constraints admits a trivial solution: the adversary “obliterates” X with a fixed, nonzero probability that depends on D2 but not on N , and therefore no reliable communication is possible in the sense of Def. 2.7 below.
