Efficiency optimization produces grammars where the orders of the eight relations in Table 1 are strongly correlated with the order of verb and object. We arrange grammars (baseline, optimized, real) by the number of relations where the language patterns with Japanese (as opposed to with Arabic) and plot a kernel-density estimate. Object–verb order leads to grammars where object patterners precede (like Japanese); verb–object order leads to verb patterners preceding (like Arabic). Baseline grammars show no such correlation.
