I recall seeing in the movie A Beautiful Mind a scene where a group of colluding men improved their dating outcomes by instituting and honoring one rule: "nobody goes for the best one". Nash demonstrated his game theory concept, and it worked the exposition into the screenplay without going too deeply into the math.

So females should probably collude to enforce dating-monogamy, to encourage males to clearly commit or reject. Polygamy works only when females judge 1/Nth of the attention of the best males to be worth more than 100% of a lesser male. Polyandry doesn't work well, because the males have negative incentive to participate--why compete over one woman when those men could just compete on the same terms for all women?

I can envision a system wherein all the women establish a ranking of their top prospects, and an algorithm deconflicts their preferences, such that only one woman can contact a given man through the system at one time, until one or the other publicly repudiates the match. If a woman expresses her preference for only alphas, she may be in a situation where she cannot contact any of them, because they're all "busy" at the time. If she tags a bunch of betas--or even omegas--she might be able to date several of them concurrently. It forces the males to judge based on "good enough for me, or not" rather than "better or worse than potential alternatives". The women would always be dating "the best available that does not compete with the other women".

It's just not realistic to implement a symmetric experience on dating apps.
