+    topics:
+    * add more algorithms
+    * document how algorithms are to be added
+    * Network X <---> LAGraph
+    * look at cuGraph
+
+    * better kernels in GraphBLAS (GxB):
+        - 'aggregator' monoids, (community detection needs mode)
+
+            c = A*x
+            monoid: "mode" (not a monoid)
+            mult:   second(aij,x) = x
+
+        - GrB_Vector-based method for GxB_select of a matrix
+            (need by scc, and more)
+
+            select op:
+                depends on parent, dense vector
+
+                keep a(i,j) if parent(i) == parent(j)
+
+        - workvector format for GrB_Vector
+
+        - JIT
+        - CUDA, SYCL, ...
+
+    * add to SuiteSparse (cmake mods)
+
+    * Intel DevCloud -- benchmark GAP: Saphire Rapids
