-Flixopt supports several calculation modes. The default mode performs full time-resolved optimization. Aggregated modes use clustered typical periods, following principles discussed in the literature on time-series aggregation ([@TSAM2020]), reducing computational burden for long time horizons. A segmented mode decomposes large operational problems into smaller, sequentially optimized blocks.
