v1.1.0

What's Changed

• Support for gene invariant version (discrete GOMEA only) as described in: https://arxiv.org/abs/2506.15222
• New benchmark problems: Bimodal Deceptive Trap, Hierarchical Deceptive Trap (HTrap), Hierarchical If and Only If (HIFF)
• Asymmetric versions of Deceptive Trap and HTrap benchmark problems
• Supported similarity_measure for linkage models: ['MI', 'tight', 'VIG']. Linkage models learned based on mutual information, distance in genotype, and variable interaction graph, respectively. In BBO, similarity measure 'VIG' can be used when fitness function implements similarity_measure(var_index_a : int, var_index_b : int) : float.
