The choice of data structures for the internal representation of terms in logical frameworks and higher-order theorem provers is a crucial low-level factor for their performance. We propose a representation of terms based on a polymorphically typed nameless spine data structure in conjunction with perfect term sharing and explicit substitutions.In related systems the choice of a-normalization method is usually statically fixed and cannot be adjusted to the input problem at runtime. The predominant strategies are hereby implementation specific adaptions of leftmost-outermost normalization. We introduce several different-normalization strategies and empirically evaluate their performance by reduction step measurement on about 7000 heterogeneous problems from different (TPTP) domains.Our study shows that there is no generally best-normalization strategy and that for different problem domains, different best strategies can be identified. The evaluation results suggest a problem-dependent choice of a preferred-normalization strategy for higher-order reasoning systems.
