C # - CardChooser
Sumário
Este aplicativo usa um método de força bruta para tentar resolver cada lista. Primeiro, crio uma lista de cartões em potencial para selecionar e, em seguida, determino qual é o melhor ajuste (remove o máximo de caracteres + reduz as palavras longas), adiciono isso a uma lista de resultados e continuo com esse processo até selecionar os cartões em potencial para remover todas as palavras da lista, eu recompensei esses cartões em cada palavra e imprimo a saída.
Se você deseja ver uma versão mais limitada desse código sem fazer o download e criar o aplicativo de formulários do Windows fornecido, pode usar o link fornecido para executar meu programa em conjuntos menores de dados, observe que esta é a versão do aplicativo de console, portanto, o resultado cartões NÃO são rotacionados:

Histórico de Revisão
Atual - Adicionado melhor otimização de resultado sugerida por @Zgarb
Atualização 3 - Mais limpeza de código, mais bugs corrigidos, melhores resultados
Atualização 2 - Windows Forms, saída mais detalhada
Atualização 1 - Novo / melhor suporte para simetrias de caracteres
Original - Aplicativo de console
Exemplos
acr, popa, ain, sll, vitória, digamos, disse, rápido, épico
hes, vai, com, não vai, iria, não iria, ainda, você, você, você
aaaa, bbbb, cccc
Código
Ainda preciso combinar isso em um projeto maior com o código ConsoleApp e WindowsForms, todos compartilhando as mesmas classes e métodos, e depois dividir as diferentes regiões no método RunButton_Click para que eu possa escrever unidades em torno delas, de qualquer maneira, sempre que encontrar tempo para fazer isso. Vou, por enquanto é isso que tenho:
