Use complete sentences unless the question says otherwise. If you did the greedy solution and took item 0 (8, 4) and then item 1 (10, 5), you couldn't take any more items and your total value would be 18. Using a biologically realistic spiking model of the full CBGT circuit, we demonstrate how this solution can allow a net- work to learn to select optimal targets and to relearn action-outcome contingencies when the environment changes. If not . One difficulty is that if credit signals are integrated with other inputs, then it is hard for synaptic plasticity rules to distinguish credit-related activity from non-credit-related activity.
