The compare harness shows MOEA/D is the single most consistent
performer: top-3 on every multi- and many-objective table (convex,
disconnected, spherical and linear fronts; 2 through 10 objectives) and
fastest or near-fastest every time. No other algorithm is close to that
consistency. This matches the literature view of MOEA/D as a strong,
robust, scalable baseline -- with the known caveat that weight-vector
spread can leave gaps on highly irregular fronts (the DTLZ/ZDT suite
doesn't stress that).
But both decision trees buried it: the README filed it under "Want
decomposition / weight-vector style" -- a stylistic branch -- and framed
it as a speed pick; the book left it out of the TL;DR table entirely.
Meanwhile NSGA-II was the listed 2-3-objective default despite losing to
MOEA/D on every table and collapsing past ~4 objectives.
Both trees now lead the multi- and many-objective branches with MOEA/D,
keep NSGA-II as the well-understood alternative and the combinatorial
go-to, add MOEA/D to the TL;DR / quick-reference tables, and soften the
NSGA-III "strong default" framing to match the data.
