The next generation of matching algorithms

The evolution of aircraft engines and the next generation of matching algorithms for the Online Dating Industry.

Aircraft propulsion

- Shaft engines (to drive propellers, rotors, ducted fans, or propfans)

A) Internal combustion engines:
A.1) Piston engine
A.2) Wankel engine
A.3) Turbines: Turboprop / Turboshaft

B) External combustion engines: Steam-powered

C) Electric

- Reaction engines

D) Turbines:
D.1) Turbojet
D.2) Turbofan

E) Rocket-powered

F) Motorjet
G) Pulsejet
H) Ramjet
H.1) Scramjet (supersonic combustion ramjet)
Unlike a typical jet engine, such as a turbojet or turbofan engine, a scramjet does not use rotating, fan-like components to compress the air. No moving parts are needed in a scramjet, which greatly simplifies both the design and operation of the engine. In comparison, typical turbojet engines require inlet fans, multiple stages of rotating compressor fans, and multiple rotating turbine stages, all of which add weight, complexity, and a greater number of failure points to the engine. It is this simplicity that allows scramjets to operate at such high velocities, as the conditions encountered in hypersonic flight severely hamper the operation of conventional turbomachinery.

The scramjet can efficiently operate at extremely high speeds: theoretical projections place the top speed of a scramjet between Mach 12 and Mach 24, which is near orbital velocity.
The fastest air-breathing plane is a Scramjet design, the NASA X-43a which reached Mach 9.8.

Sometimes I read posts about a "fairly complex matching algorithm" for online dating
receive emails promoting "a sophisticated algorithm" and then I laugh!!!
Matching algorithms do not need to be complex or sophisticated, they need to be effective.

Those complex or sophisticated matching algorithms (used by eHarmony, Chemistry and others) are like the Wright R-3350 Duplex-Cyclone used in the Boeing B-29 Superfortress, useless at all to ....... break sound barrier!!!

Actual matching algorithms used by eHarmony, Chemistry and others, even behavioural recommender systems, can not be improved, they need to be discarded NOW. Because they are in the range of 3 to 4 prospective mates as selected / recommended / compatible for dating purposes per 1,000 members screened in the database. They all 3 are performing the same for serious daters, with a high percentage of false positives, like gun machines firing flowers.
They can not break the online dating sound barrier!
You do not need to improve a piston engine when you need a jet engine to break sound barrier.

That range convergence phenomenon is what I had called "the online dating sound barrier", in 2003, when I had discovered than problem, 8 long years ago.

It is only strict personality similarity. A Scramjet engine.

The Online Dating Industry for serious daters needs a revolution, but without offering the 16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry.

The 16PF5 normative personality test codifies personality with 16 variables taking integer values from 1 to 10 in stens (standardized tens).
The ensemble (whole set of different valid possibilities) of the 16PF5 is: 10E16, big number as All World Population is nearly 6.7 * 10E9
A high precision quantitative method to compare similarity between those quantized patterns is required to successfully break the online dating sound barrier.
